Huh, I like the way you phrased that: "abandonment of US soft power in the world". But I think there is also punitive aspect: they are intentionally "punishing" the people at NIH they perceive as being liberal and favoring other countries.
It's a good point. There is a target on the back of scientists who do research that is perceived as social science but is infact biology. Seems like they then construct myths of waste/corruption (just read this thread) and punish everyone.
