What Trump is threatening to do on tariffs -- what he has already done! -- is completely illegal under the GATT/WTO. By signing the disgraceful Turnberry deal which was also illegal, the EU was helping to destroy the rule-based order. For that reason alone it should not be allowed to resurface.

and yet some escalation would actually be positive, or else the threats (and actions) will get worse. That's how bullies operate.

We (@julianhi.nz @ckhead.bsky.social @schularick.bsky.social & I. Méjean) made this point in July, and it only got worse since then:

The war will end when Russia stops fighting. Therefore, pressure has to be put on Russia, so that they stop believing that they will win. Why is that so hard to understand?

the way we think about is that historical borders limited mobility and this generated social networks with relatively few cross-border links. but all the legal/frontier barriers are gone in EU. so we want to est. a partial effect of borders conditional on the social network legacies. open to ideas.

These are good points to keep in mind. What would you suggest? The thing we want to estimate is the part of the border effect that government policy can reduce. There are no current regulations that limit cross-border friendship in Schengen EU.

RFK Jr.'s claim that vaccines didn't save lives, sanitation did, is half right—and dangerously wrong.

While sanitation helped in the early 20th century, vaccines saved millions of lives in the later 20th century and reduced severe impairments like brain damage. More in @statnews.com
RFK Jr. says vaccines don’t save lives. He’s wrong
Now RFK Jr. is claiming vaccines don’t actually save lives. Here’s the math to show what he gets wrong.

I cannot overstate how remarkable it is that under GOP rule, US federal health regulations have been captured by fringe crackpots who espouse views that the vast majority of the US public—and nearly 100% of health professionals—reject.

Because of Florida's decision to phase out childhood vaccine mandates, many will die of preventable diseases like measles, chickenpox, tetanus, and diphtheria. This is regressive, bringing us back to the early 1950s when parents had to worry that their kids might die from diseases like polio.
