European here.
This comment takes assumption that by "US falling to fascism" you meant Trump taking control of the USA. Please ignore everything if I misunderstood.
Trump's among the few US presidents that didn't start a new war. Source: https://www.reuters.com/article/idUSKBN2A22QR/
He also scaled down wars in Afghanistan, Syria and Iraq. I AM NOT SAYING THOSE ACTIONS WERE GOOD OR BAD FOR THE USA, or for the rest of the world for that matter. And I'm really not qualified to discuss that.
This comment is ONLY a direct reply to a concern that Trump's rule should have Europe worried in the sense that he'll nuke us.
Maybe someone else nukes us as a consequence of his inaction, idk. But Trump nuking Europe is what you said, and I disagree.
