Into the 1920s and early 1930s, Germany seems to have been a/the center of research, culture, etc. The rise of the Nazis shut down research that conflicted with their political goals and researchers left for free countries, especially the US. The US, perhaps the only wealthy place on earth after WWII - it devastated Europe - has been the center of research and culture since then.

Now in the US, right-wing powers have campaigned to shut down disinformation research, often via lawfare and apparently via influence on major universities. Also, the Trump administration has made clear it is against much scientific research, especially when results conflict with political goals, and has already interfered in significant ways with research (and also culture). I think the Trump administration would agree with that description.

There's no war yet that will devastate the US economically, but the Trump administration is willing to risk that. Even without a war, it's not hard to imagine disinformation researchers moving to Europe now, and also scientists and also artists generally. Again, I think the Trump administration would endorse that.
