This is how fascism operates. In the 1930s the Nazi regime enforced strict control over academic institutions, censoring research and silencing dissenting voices. Many left Germany: Einstein, Born, Hahn, Meitner, Schrödinger, Szilard etc. etc.
Today, US scientists are looking at moving abroad.
@rahmstorf Future Nobel prize laureates will come more and more from China, that's my estimate. Maybe that's a too wild guess but I think at least that the US will lose its pole position on that in the long run if this disregard for the scientific method will remain part of gouvernmental policy (see also Kennedy's nomination for the public health ministry).
