> many countries are increasing funding substantially (e.g. [1]).

This illustrates exactly my point. Canada is planning on spending up to CAD$1.7B over 12 years. That is equivalent to USD$100M per year, or 0.3% of the NIH 2026 budget. Maybe if Europe does something similar they can get to 2%!

I agree that Trump's regime has made the US a less welcoming place for foreign scientists, and that budget cuts mean less research will be done. What I disagree with is the idea that "brain drain" is a significant threat to US science. We simply have such an incredible oversupply of biomed PhDs that we should welcome the prospect of other countries absorbing the supply.
