The logic to think that prenatal Tylenol causes autism and ADHD

Leave a reply

Robert Kennedy Jr. recently started the process to add a warning to the labels of acetaminophen products, including Tylenol, noting a correlation between its use during pregnancy and autism and ADHD in children. The advisability of this is controversial. Experts at Scientific American say “the evidence against Tylenol is thin,” The British Journal, Nature, goes further: “It’s Dangerous to Avoid Tylenol While Pregnant”. Similarly, Barak Obama: “Trump’s announcement is violence against the truth.” Nature’s logic, and Obama’s, is that any risk of Autism and ADHD is smaller than the risk to pregnant women if they do not take fever medication. Given the confusion and politicalization of the topic, I thought I’d write about the magnitude of the risk, and the logic to think Tylenol causes autism and ADHD.

The evidence that there is some, large risk agent is the tremendous rise in the prevalence of autism and ADHD over the last 50 years, see chart above. The rise t matches the rise in the use of Tylenol as opposed to older medications, like aspirin. Correcting for other changes (confounders), this Oxford study finds 95% certainty association of acetaminophen with ADHD; care being taken to remove confounders. Also of note is that, none of the studies suggesting was Tylenol is safe for pregnant women looked at neural development damage in children. None.

In terms of the magnitude of the Tylenol effect, this study from Johns Hopkins, compared fetal blood levels of acetaminophen enzymes (measured in the umbilical cord) to the risk of autism and ADHD. As shown below, there is roughly a three-times increase in risk for both in every sub-group of child: male and female, black and white, pre-term and full term, drug user or not, breast fed or not, fevered mother or not. Children with higher blood-acetaminophen levels (2nd, 3rd tercile) always have a higher chance of ADHD and ASD — about 3 times higher– than children in the lower tercile.

The higher cohorts of blood Tylenol is associated with higher risk of ASD and ADHD for every subgroup.

This European study found a similar association, but measured Tylenol use based on interviews. Between these studies, I find it reasonable to advise caution. This is the sort of evidence that caused us to put cancer warnings on cigarettes, caused us to caution against alcohol during pregnancy, and caused the mandate for seatbelts. This is usually what scientists use, it’s the best approach we have. I do not suggest dropping all fever medication, but suggest switching to older medications, like aspirin, or cool showers, or following the Harvard medical journal advice to take Tylenol in the minimum dose.

An upside to the political divide is that we’re likely to have better evidence in coming years. in Republican-leaning states, doctors have mostly favored the advisory. Meanwhile,in D-leaning states women are ignoring the advisory, some even filming themselves taking extra Tylenol, in distain for Trump. These two groups provide a controlled study, so that we should have have better data regarding Tylenol safety in 2-3 years.

Thomas Kuhn, and why half of America loves/ hates Trump

Leave a reply

This post was inspired by articles like the one below asking how it was that some Americans, MAGAs think Trump is good when everyone of value sees him as a fat, bigoted, criminal clown. The Atlantic’s answer is they’re detached from classic ideals of good or moral, and are now fueled by “narcissism, fanaticism, and authoritarianism”. I thought a more helpful explanation was that we’re going through a paradigm shift, perhaps progressing in our thought of what it means to be good.

Consider Thomas Kuhn’s analysis of scientific progress. Tomas Kuhn was a major American Philosopher of the 1960s-70s who claimed that science progress was not uniform but included long periods of “normal science” punctuated by change. A “crisis” leading a “Revolution” resulting in big changes in language, outlook and thinking, a “paradigm shift”. In the midst of these scientific revolutions, the experts of the old system fight bitterly against the new while being confounded by the fact that it seems to work.

Consider the resistance to relativity and quantum mechanics. Before 1905 the experts were doing fine: Professors taught and students learned — formulas, tools and techniques were handed over. Educated had respect and money, and could communicate. There were some few contradictions, as in why the sun burned hot, or why the sky was blue, but one could ignore these. You knew who the experts were, and they didn’t include Einstein, Bohr, Pauli, Plank.

Democrats sell red hats and buttons with Fascist or Felon because Trump’s red MAGA (Make America Great Again) hats work for him.

But then came a few more problems, (inconsistencies in Kuhn-speak: radioactivity, photoelectrons, the speed of light… Einstein published on them in 1905, thoughts that few took seriously: imaginary time was a fourth dimension at right angles to the others, etc. The explantations seemed mad and for 14 years after he published, Einstein could not get a university job — anywhere. By 1919 detailed experiments suggested he might be right on a lot of things. It lead to the rise of a new group of experts plus a loss of esteem for the old, and a bunch of crank explainers who were neither but flourished in the confusion.

Hate abounded; new weapons and cures WWI removed aristocrats and beards. A popular book a lecture series of the time was “100 scientists against Einstein.” There followed a lost generation with no clear foundation. It took 50 years to resolve confusion, but there developed new thought leaders, a new language, new standard formulas and books were sold, and we were returned slowly to “normal science” in a new thought paradigm.

I see the conflict of opinion surrounding Mr Trump as a crisis in political thought similar to the crisis in science thought 100 years ago. Polite discourse if gone, replaced by stunts and insults. The government is currently shut, with 40% federal workers, those whose jobs are non-critical, on unpaid leave. It’s a collapse, not of morals, but of language. Trump hopes to use the shutdown, I think, to show that most of these 40%, are not needed. If they are not needed, it reflects a big lack in government — actually a big bloat in government. You can see why the opponents of cuts see Trump as a fascist who uses “dog whistles” to motivate “his base”, there is a lack of communication and a fear Trump may be right too, I think. The experiment in smaller government is being run as I write, and Trump seems confident that some 400,000 federal workers are not needed. Are they? Instead of debating, we’ve got to violence: two attempts on Trump’s life so far, the main college debater, Charlie Kirk, shot dead. Appropriate, I think, is Bob Dylan’s, “Times are a-changing” and “something is happening here, but you don’t know what it is, do you, Mr Jones.”

Other questions are being worked out as we speak -sending chills through the old order: Are China and Europe “ripping us off,” by free trade and stolen technology? Are tariffs an answer. Canadian and European leaders deride these thoughts openly, but I notice that both Canada and the EU have put heavy tariffs on Chinese goods.

Another issue is respect for experts. The Atlantic bemoaned that Trump supporters don’t respect experts on health, climate, and education, but perhaps they are lying. The seas have not risen as expected. Some warming may be good, or better than the remedies. Even if RFK Jr.’s ideas are wrong it seems that science has become unreliable (irreproducible), and that elite colleges aren’t fair in their assessment, nor do they provide great value.

Eventually things will settle down; we will some day have polite discourse. In 40-50 years, I suspect we’ll agree that some tariffs are good and that Trump’s tariffs are either to high or low, We’ll think that the climate push to no nuclear power, was a mistake, as was the giant, Ivanpah solar farm). And we’ll be able to discuss it civilly. I hope the change in thought takes less than 50 years.

Robert Buxbaum, October 3, 2025 – we are now entering another physics crisis too, I think.

Purifier delivered to customer for muon-catalyzed fusion

Leave a reply

I got my PhD in the engineering of nuclear fusion reactors (Princeton 1982). The most common version of these reactors use magnetic confinement. Rare isotopes of hydrogen are held in a magnetic bottle at 300 million °C (30 KeV), reacting to produce helium, useful energy, and a neutron. The magnetic bottle and high temperatures are necessary to overcome the repulsion between the hydrogen atoms at the distances necessary for nuclear fusion.

A customer of ours is building a different type of fusion reactor, without high temperatures or a magnetic bottle. They replace a few electrons of the hydrogen with muons — particles that are like electrons, but weigh about 207 times more. Hydrogen fusion is quickly catalyzed, as described in an earlier post. The muons recirculate to catalyze more until they decay or are trapped by an impurity, often helium. 

Our company, REB Research, just shipped a specially made, hydrogen purifier tailored to remove the impurities in this process. Another aspect of the purifier design is that it minimizes radioactive tritium leakage, something that happens when hydrogen (tritium) diffuses through metals. We wish them all success, and wish success to our other fusion customers as well.

Gerrymandering, old-politics, fairer versions could be worse than less fair

Leave a reply

There is no truly good way to give representative voices to a population. The founders of the country decided that there would be a set number of congresional representatives, divided it by states, and left it to the individual states to subdivide, with a few provisos. They mandated that congressional districts have to be contiguous, entirely within a state, and contain approximately the same number of citizens in each. A later law specified that the districts should not directly disadvantage a racial minority. Within these parameters, legislators in most states have divided congressional districts to advantage those in power to a greater or lesser extent. The most egregious of these are Gerrymanders, odd shaped districts that protect sitting congressmen and parties, as bad as the worst of these are, they are better than some, truly awful, “fair” divisions, in my opinion.

This was Michigan’s district map (Detroit area) until redrawn by independent commission, 2022. My district was the dark blue one that looked like a man in a chair.

Consider my state: Michigan, a swing state that voted for both Biden, and Trump. Currently the state house is 52% R and 48% D, but Democrats were in majority as recently as 2024. Our congressional district map used to be a disaster, shown at left. In 2022 it was replaced by a map created by an independent committee that aimed for roughly square districts that aimed to keep towns and communities together. The result is that most districts are either safe D or safe R. This, we’re told, is bad in that it leads to factionalism, with congressmen pandering to political extremes, with little incentive to compromise.

A fairer alternative (?) would divide the congressional districts so that all or most district are swing, like the state. Supposedly such districts would elect moderates who compromise. This version, though no-less fair than the above, is not good, in my opinion. I expect it creates chaos and turnover. I’m also not convinced that compromise is always best.

Pennsylvania’s congressional map before redistricting by independent committee. Ugly, but fair in its way.

The variant of this that preceded our current is for congressmen and others in power to create districts that are fairly safe for themselves and their party, leaving those of the other party in a few, super-concentrated districts. This division is less fair, but far more stable and workable. It lead to ugly gerrymander districts in Michigan (left) and Pennsylvania (below). This is not bad in itself. What was bad about these gerrymanders is that the congress folk, secure in their jobs, formed a political aristocracy. Seats passed from generation to generation, and ruled fairly disconnected from the wishes of those they represented. A good part of the aristocracy is that they worked well with each other, across party lines. They were friends, alumni of the same schools, members of the same churches and country clubs. They were good-‘ol-boys, who didn’t pander nor embrace ideological extremes. Writers romanticize this, but I’ prefer our current’m glad it’s going in MI.

California and Texas politicians are pushing for more gerrymandering. California’s congressional districts were drawn by independent committee. Their governor called the Trump White House fascists as recently as today. There’s a vote to get five more D-districts. The claim is it’s to balance Texas’s push for three more R-districts. I nothing illegal or immoral here, just old style politics, power grabs left and right, with incendiary language. The districts look bad, but I’ve seen worse. No need to call ‘fascist’ unless your next step is to impeach president Trump again, or your hope is another shooting.

The worst option, in my opinion is term limits. It’s promoted from both sides, and I consider it insane, except for party bosses. It actively prevents people from re-electing the politicians they like based on the objection that these people have been on the job long enough to feel at home and get things done. I consider term limits completely non-republican, non-democratic, a disease, “fair” only in that it hurts every citizen equally, benefitting only party bosses.

Korean movies and music; my thoughts on why they do so well

Leave a reply

A Korean animated movie, K-Pop Demon Hunters, KPDH, just broke all-time record for most watched movie in the History of Netflix. It’s only 92 days old, and not a big-budget film with massive marketing, but it’s had over 314 million views so far, appearing on the most-watched list in 32 countries. Some Chinese movies have had more views, but these tend to be specific to China, with limited appeal elsewhere. KPDH has three songs in the Billboard 100 too, including golden at no.1, see official music video, 352M views for the music video. The last movie to have three songs in the Billboard top 100 was Saturday Night Fever, some 45 years ago. Other top Korean groups include Stray Kids, BTS, and Black Pink, they’ve had multiple #1 songs world wide of the last five years, and fill 50,000 seat stadiums regularly with seats going for $150. Here are Black Pink, filling a 50,000 seat stadium in Paris. If you read the US press, you’d hardly know these groups exist. BTS had a big hit during Covid called, “Permission to Dance,” a positive song during that grim period, danced e.g at the UN. Listeners noticed, the press did not. I think the press finds Koreans “anodyne”, that is, insipid.

Top movies of the last 20 weeks include two Korean offerings, Squid Game and K-Pop Demon Hunters

One thing that turns off the US press, is that Korean songsters and movies are less sexual, and less politically moralizing. The top Oscar awards go to political movies. At the Emmies, this year, we were told, “F*ck ICE, Free Palestine.” Similarly, Green Day, Eminem, and other western bands lead chants of F*ck Trump. The press takes this moralizing as intellectual, but I find it cheap and suspect it turns off many potential fans.

Director of Star Wars, Kennedy, promoting diversity.

A favorite moralizing of US movies is to show women who don’t need or want men. Frozen was like that, as was Encanto, Last Dragon, Moana… Star Wars was a top franchise that Disney made more feminist, writing basically every man as bad. Women were good, powerful, and inherently talented. Rey a main new character, grabs a light saber with no background or training, and uses it like an expert. It turns off men, then women stayed away too.

End kiss of Pirates of Penzance, the pirate prince and the major general’s daughter

We like to show black actors in white rolls too, though not white actors in black rolls. Hamilton was successful, and had black actors playing in every positive roll, white actors playing evil idiots. It was done again with 1776, less successfully. All the founding fathers are cast as women; Jefferson is black, bisexual, and pregnant. There’s a message somewhere. The upcoming movie about King Gustaf of Sweden has a dark-skinned actor playing the king. Why? We had a dark- skinned daughter of the major general, who bends the pirate over to kiss him, a dark skinned Snow White with most of the Dwarves normal height, a female She-Hulk, stronger than the original, who lectures the original (and us) about anger. Apparently, the idea is to highlight the difficulties powerful women face. Korean shows have casts that make sense to the plot, and no gratuitous reversals or sex. Did Oppenheimer need the many sex scenes? Did the suicidal love interest have to be written stronger than the main character?

Then there are the sequels: the Marvel universe includes 37 interconnected movies, Star Wars, 19, Batman 13. To get the full story, you have to see them all. So far, in 2025, only two of the major funded movies were original (one was Korean, Mikey 17). The others are all reboots or sequels with recycled plots and ever-bigger explosions. It all works until it doesn’t, then they make a reboot. Law and Order, 26 years old with 500 episodes.

Scene from Crash Landing on You. These two are in serious trouble.

Korean entertainment has series too, but much shorter and with fewer explosions. A TV series will have only 16-24 episodes and I’ve yet to see one with a mass-murderer. The Squid game, has had 13 episodes over 3 seasons. Some deaths, but not wholesale. A longer series, “Crash Landing on You,” 24. In it, a successful South Korean executive (female) is blown across the border to North Korea into the arms of a handsome, North Korean. No deaths. They could have gone on for years, but didn’t. People rewatch the original.

Other countries movies moralize too, like ours do, but they tend to be patriotic moralization, and anti gratuitous violence, not violent, anti-patriotic as in the US. Chinese TV shows present Chinese politicians as honest, they have praise for the Chinese schools and infrastructure, and regular invocations to respect the police. India moralization is similar, but more towards family order. Korean messages are in-between, with some crooked politicians, some violence, people with mental or emotional problems who evolve.

Robert Buxbaum, September 17, 2025. The industry has pushed back against criticism of their wokeness, claiming that the only folks turned off are the toxic fans: white, MAGA men, mostly, who hate diversity. They claim to be happy when such fans stay home and watch KPDH, or go buy $150 tickets to see Koreans sing in Korean.

Kamala’s positivity; Gavin’s MAGA tears

1 Reply
Harris presents is something of a unifier.

Kamala Harris always seems happy while most Democrats come off as sad, and report being sad. Harris’s campaign also stood out from Clinton’s and Biden’s for positivity. She never played the racism card, or the feminine glass ceiling card, and still managed to raise $1.5 B, some three times more money than any other candidate in history. In a campaign of only 108 days, she focussed on the swing states, inspiring support from the press, comedians, academia, Socialist Bernie Sanders, and the billionaire class: Mark Zuckerberg, Bill Gates, Jeff Bezos, etc. Quite a mix. She lead in the polls to the end, barely beaten by a seasoned, media-savvy Trump, running effectively as an incumbent. I suspect she’ll be unbeatable in 2028, if she’s allowed to run.

Harris has some minor down-sides, all of them related to her positivity. First off, Harris comes across as somewhat dim-witted. That’s annoying to political junkies, but not really a problem for most Americans. She comes across as having a good heart, and that’s enough. We elected George W. Bush and Joe Biden, dim-witted, likable guys, who people we related to. Brains can even be a handicap: we voted out George H. W. Bush, despite his brains and expertise, even after he’d taken down the Berlin Wall. It helps to have competent helpers, and Kamala stayed close to Obama and Cheney. Her VP failed to impress, but she’s sure to pick better in 2028.

Harris also comes off as drunk; she giggles a lot (AOC too). It makes them seem young and insubstantial. I find it annoying, but not deadly. It’s a way around tough questions, Rather like Regan’s jokes, or Trump repetitions. Hilary campaigned as a good, heavy smart and mean. Her “basket of deplorables” comments, for example. They must have sounded OK for those already on her side, but they sound mean and dismissive to everyone else. Harris will need a signature issue by 2028, but is sure to find one. Free everything seems to be working for Mamdani in NY.

None of the other top D contenders for 2028 are anywhere near as likable as Harris. Gavin Newsom comes across as smart, but mean. Not too smart, but as mean as Hillary. His current push is to redistrict California to fight the Republicans. That’s smart but not inspiring; people of California will loose their representatives so the democrats can gain power. Then there are the photos he puts out of himself drinking “MAGA tears.” The idea he’s pushing is that Republicans are cry-babies, while he’s a man’s man, and that he enjoys making MAGA folks cry. It’s dismissive of the suffering (real and imagined) of the rural, less rich, less educated, white folks — the folks who are the core Republicans. He also calls them “The base,” and that’s another slight; they’re people, often hard working, disrespected, with uncertain job prospects, from communities that are unusually hit by prescription drug addiction. Harris knows enough to care or pretend to care.

A staple of Newsom’s campaign, him smiling, drinking “MAGA tears”

I don’t see Newsom as particularly manly, either. He looks less virile than Vance, who he targets as a compete wimp. Newsom recently published pictures with Vance’s head photoshopped onto a skinny female dancer. Is that funny? Is it true? Vance is an ex- marine. That’s the sort of manliness credential that Newsom doesn’t have, and is rare among Democrats. Not that I see America preferring manly men, but Newsom should know enough to not to get into a manliness fight with a marine.

And that brings us to baggage. Harris has relatively little. Newsom has the California fires that he screwed up by diverting water. He has ownership protecting high crime, the homelessness by fighting ICE and The national guard. He also has the baggage of California’s, high taxes, high regulations, high energy costs, and population flight. California keeps needing to borrow money, and in this, I doubt it helps that he’s made illegal immigrants a priority. He could acknowledge that Trump has reduced crime, as the DC mayor has. Harris has mostly avoided speaking on these issues, and it seems to help.

No empathy for Charlie Kirk from Manitoba’s Minister of Families

Other Democrat heavyweights are as bad. Walz says he checks his phone every day hoping to see that Trump is dead. He also claimed to enjoy news that Tesla stock is down. Illinois Governor Pritzker, here, blamed Trumps heated rhetoric for the murder of Charlie Kirk. Then there are those like the MSNBC host or CNN’s who blamed Kirk himself. Or this, from Manitoba’s Minister of Families. It’s mean, untrue, and not even self serving. Harris comes off as the best among the Ds, and the most electable.

Robert Buxbaum, September 12, 2025. I’m a New Yorker, and I like Trump’s accent, his brashness, his tariffs and peace initiatives — and that he backs Israel over Palestine. A lot of people can’t stand him though. Folks are likely to elect a Democrat in 2028 — so long as the D candidate doesn’t claim to drink MAGA tears or watch to see Republicans dead.

98% Certainty that Trump has reduced crime in DC

1 Reply

It’s been 24 days since Trump sent the national guard into DC, and the crime rate has dropped by a factor of six. The murder rate went from 101 murders per year in 2024, one murder every 3.6 days, to one murder in 24 days. I find that the odds of this being coincidence is less than 2%. Car theft and other crime has dropped as well. I consider murder rate the best metric for crime because no murders go unreported, and none get misclassified as altercations or misunderstandings.

Using the National Guard to maintain order is not that unusual. Eisenhower sent them to Arkansas in opposition to the governor to ensure desegregation. LBJ sent them to Chicago to protect the Democratic convention of 1968.

To figure the odds that this improvement is coincidence, consider that the odds of a murder on any one day is 101/365 = .277. Based on this, the odds of no murder on any of particular days is, 1-.277 = .723. On any given day in DC it’s more likely to have no murders than to have a murder, but the odds get much lower for going many days without a murder, or for 24 days with only one. The chance of of having 24 days without murder, for example beginning at some set-start, would be (.773)24 = .0021 = 0.21%. The odds of having only one murder in this time is calculated similarly, as 24(.277)(.773)23 = 1.8%. This is to say that there is a 98.2% chance that the drop in crime rate is not accidental.

The D.C. Mayor Muriel Bowser had originally objected to the guard, but now is happy, or so Trump claims. If she removed them now on, she would have to argue that high crime rates are good. Other mayors may not want to be in this position.

A federal judge, Charles Breyer, just declared the use of the national guard illegal, by the way, a violation of the Posse Comitatus act of 1878 see the complete statement here. The Posse Comitatus act bars the use of federal troops for police activities, except federally related ones. Judge Breyer, decides that there is no federal justification and demands that the national guard leave within 10 days. Trump claims that various riots in DC and LA (and Chicago) constitute an insurrection, and adds that attacks on federal ICE agents and federal buildings makes it federal. Judge Breyer recognizes that many other presidents have used the guard for law and order, even in opposition to the governor. Eisenhower for example, or LBJ to protect the Democratic National Convention 1968, but sees no justification, here or (it seems) for Eisenhower or LBJ either. Judge Breyer seems to believe they all acted illegally. I don’t know enough law to judge, but recognize that allowing Trump to reduce the crime rate makes mayors and governors look bad. Detroit crime is awful, as is LAs, Chicago’s…

Tariffs on German cars are inflationary, but not for you.

Leave a reply

As things stand, the major export of Germany to the US is high end cars: Mercedes, Audis, Porsches, BMWs, $100,000+ on average. The lower end models are made in the US, Mexico, and Canada. These high end cars are the biggest profit centers of their makers and of the German economy. Currently, they face an import tax (tariff) of 15%, the same as everything from Germany (or Italy or Japan). Liberal economists are furious at this; they claim it’s a tax and that it is inflationary. They are right on both counts except that this is only a tax and inflationary for the few Americans who buy new, high end cars.

The Americans who buy such cars are typically rich folks — poor and middle class folks can’t afford them. They are also folks with ‘taste’, folks who need a BMW, and would not be caught dead behind the wheel of a US car. Normally liberal economists would favor taxing such people, but these are often the who hire economists. They run the TV programs and newspapers, universities and hedge funds. They choose the economists and the economists are eager to see things their way.

Another high tariff item imported from Europe is art. Modern art for $1 million dollars that ends up in museums. For the average Americans the tariff on this, or on art is irrelevant or beneficial. The income it generates is used to offset other taxes, allowing Trump to remove the tax on tips, for example. That this tariff falls on rich people and replaces a tax that otherwise fell on poor workers. Liberal economists should favor of this, but their opinions are not their own.

A side benefit of these tariffs for ordinary folks, is that that they cause some buyers to switch to American-made products, cars and art. Perhaps not for themselves, but for for their children. They may buy a German car made in the US, rather than one made in Germany, or art from an American. This provides jobs for US workers — and an opportunity for Detroit to retool for the future. Detroit auto workers seem to understand this; they voted for Trump in 2016 and 2024. Detroit’s union leaders opposed tariffs. In Michigan, the union leaders get their power mostly from MI politicians, Democrats, who force union membership.

This is not to ignore the suffering of those who buy foreign products, the buyers of new BMWs, or French cheese, or high end art. As things stand, Columbian coffee is tariffed at 10%, and that may add 50¢/lb. Mexican coffee is not taxed, but many average Americans prefer Columbian. I hope they can be consoled by Trump’s tax breaks.

Some months ago, Trump showed off a tariff schedule that he considered ideal, with rates targeted to reduce our trade deficit by half. I derive here, Trump’s formula and rates, and give my opinions of the target. By the formula he presented, the EU tariff should be higher than it is, 20%. Trump has it at 15%, I think, for diplomatic leverage, to goad the EU into lowering their tariffs on us goods, now 15%. He’s also pushed them to spend more on defense, and pushed to end the war between Cambodia and Thailand. He threatened them with near 100% tariffs if they didn’t stop fighting.

Robert Buxbaum, September 2, 2025. Here’s a Bob Dylan song, union sundown, making a musical case against free trade. Once upon a time that was a liberal view. Now not. The NY appeals court ruled to block Trump’s tariffs to stop the horrible damage being done. My guess is the judges drink high-end coffee, eat French cheese, and drive new, German cars.

Trump’s temporary (permanent?) peace between Thailand and Cambodia

1 Reply

Four weeks ago, Trump managed to pause (perhaps end?) a century long war between Thailand and Cambodia that had flared up with F16s, rocket attacks, drones, invasion, and hundreds of dead. He did it by threatening to block trade with both countries if they didn’t sign a ceasefire. Within the day, they did. Perhaps, all they needed was a good excuse to stop fighting. The peace has lasted four weeks, though nasty words continue to flow. Some 70,000 Buddhist monks are very appreciative.

Malaysian PM Anwar Ibrahim (center) hosted the peace talks in Putrajaya as chairman of the Asian regional block, Official Photo.

Thailand and Cambodia have had had significant empires with overlapping land claims going back to the days of the kingdom of Siam and the collapse of the Khmer empire. A peace treaty was concluded between 1904 and 1908, but it involved ill- drawn, conflicting French maps. Several major Buddhist temples are in the disputed areas; they appear to be part of Siam in the earlier map, but part of Cambodia in latter documents. Siam complained weakly about the later documents, perhaps signaling accent, or signaling that they had the weaker army.

The problem festered this way until WWII when Siam allied with Japan and took back the territory it claimed, plus some more. After Japan lost the war, French Cambodia took back the territory, but Siam / Thailand re-armed and re-took in when the French left. It didn’t help Cambodia’s claims that it collapsed into a rein of terror under the Khmer Rouge. As things stand, the International Court of justice favors Cambodia’s claims. Then again Thailand now has the larger army, and has used it to occupy the disputed areas.

Buddhist thank Trump for peace request he gets the Nobel Prize. Photo from USA Today. Sometimes all it takes is a hard push.

A May-July, 2025 flareup in fighting resulted in about 200 dead and/or captured, mostly in the area of the historic temples, plus 135,000 displaced. The Malaysian PM, Anwar Ibrahim, tired to achieve peace, and on July 28, 2025 Donald Trump stepped in and calling both leaders in the midst of tariff negotiations and informed them that they would be banned from US trade if they didn’t stop fighting. With Malaysian help, they signed a ceasefire that day. The presidents thanked Trump; 70,000 Buddhists marched and asked that he get the Nobel Prize. It’s the power of tariffs, and of personality.

Will the peace last? It has for four weeks now, and seems to be holding. The press downplays the significance saying that Trump only got involved because he wants the Nobel Prize. Maybe, but people are not dying who would be. Peace is good and surprisingly hard. I would not mind seeing Trump get the prize, shared with Ibrahim. My guess is that it was motivated more by ego than real hopes of gain. They were in a position to push effectively, and did so. The push was a convent excuse for sanity. A month later, Trump brokered another peace deal, this time between Armenia and Azerbaijan. The press isn’t impressed with this either, nor with Trump’s efforts to end the war in Ukraine; they’re upset over his efforts to reduce the crime rate in DC.

Trump may have made peace between Azerbaijan and Armenia; Or it might be a horrible mistake.

The Turks and Armenians have been at war for centuries. Perhaps the major event in the war was in the years leading to WWI. The Turks invaded the Armenian region of their empire, killing about 1 million. More recently, Armenia invaded Turkish Azerbaijan, taking territory including the Negorno Karabakh region, while killing and exiling 50,000. Armenia had allied in its fight with Iran and Russia while Azerbaijan had allied with Turkey and Israel. Fighting had continuing until last week when Trump signed a peace deal that involved the US private industry (Trump) building a corridor, modestly named the Trump Road for International Peace and Prosperity (TRIPP). No normal diplomat or investor would indulge in such a deal, and no normal person would commit to it. It seems certain to fail, but then again, it might bring peace to the region and money for Trump.

The logic of the deal, and why it might work, is that the wars may have not been so much wars of religion, but wars of geography. The Armenian, Christian communities are dispersed within the Muslim Turkish and Azerbaijani communities. Without their help the Armenians can not communicate with each other nor sell or receive goods. Turkish and Azerbaijani communities are dispersed within Armenia and Iran. Azerbaijan is divided in half, while Negorno Karabakh is entirely within Azerbaijan. The proposed Trump Road would allow transit and trade. Trump and colleagues would to build and defend this road, allowing trade, in particular allowing the flow of oil and gas from eastern Azerbaijan to western, and perhaps even to Turkey, implied is also free trade with Negorno Karabakh. It seems good, and the leaders of Armenia and Azerbaijan have signed their agreement. As presented, the road would be Armenian territory, but would allow free transit, though not likely of weapons from Iran.

Could it work? Trump is a magician, and sometimes he does what seems impossible. Still there is a lot that could go wrong. Even if this conflict isn’t religious, there are long simmering hatreds, and deep distrust. This is, at best couples therapy, and the one who typically loses is the peace maker. The Armenian Daily Journal has already complained that Armenia gets too little economic benefit, “just crumbs.” There is no way to please both sides, 100%.

There is also a trouble maker, Iran. Iran is in the middle of a 1000 year long religious war for control of the region. Iran sells oil and gas to Turkey and Syria, while funding revolutionaries, Hezboalh. They are not willing to see their trade displaced by Azerbaijan and the US. Iran’s leaders have threatened war to maintain their control. Iran was more threatening two months previously, but Trump punctured Iran’s nuclear program, and joined with Turkey and Israel in the removal of Hezbollah from Syria. Iran still has one card more, but it’s weaker than it was. As a member of BRICS, they have called on their BRICS allies, China, India, and Russia to help them keep the US out. So far, nothing. In a region like this, no normal person would get involved, but Trump is no normal person, and peace is good, if only for a few years (or weeks).

Robert Buxbaum August 23, 2025; A week prior to this peace agreement, Trump seems to have forced a peace between Cambodia and Thailand by refusing to negotiate trade with either until they make peace. Here’s the BBC’s take.
