This is literally the first I've heard of any of these things and whilst I'm not in North America I follow the political situation pretty closely. I'm not saying your wrong about any of it but who are the people saying this and where are they saying it? Has it been reported on either internally or externally to the US?
The overall playbook is fascist I agree but the situation I was trying to compare was Hitler invading a sovereign nation. Trump hasn't done that (yet anyway). I've got good friends in the US and I am very worried about them, I'm just not sure you're betting on the right horse by asking for outside nation-state aid. Rightly or wrongly they'll see that Trump was elected legally and they're never going to invade a country on that basis. There was zero talk of repercussions for Germany until Hitler invaded Poland because he followed the democratic process (or successfully manipulated it) to get elected and assume total power.
