This is of course appauling misguided and actually very unAmeircan. America is the same country that took loads of ex-Nazi scientists into the US after the second world war to boost their industries - most notably for the exploitation of space. To now be doing the reverse - presumeably for the least skilled and useful (I dont see Elon Musk being deported) is just part of this mind set. It may benefit the US in the short term but I think in the longer term it will hugely damage their international reputation. The last country to do this sort of thing - though obviously in a more barnaric way as time went on was of course Nazi Germany.
