What the hell is Trump admin trying to achieve here? China was already overtaking the US in scientific research. Randomly detaining researchers just because they're foreigners (among other things like defunding universities) ensures that in 5-10 years US will be hopelessly behind on everything from social sciences to medicine to physics, the list goes on really, and not just behind China but likely behind EU too. This really does seem like an empire in decay, however I'm willing to bet that people working on missiles to kill brown children will continue to be well-paid until the bitter end.
