Yeah, as I edited and added in my previous post above, Europe isn't used to being disrespected the way Trump so blatantly has. They're used to having the US pay for its continental security and used to having the US basically set up the global economy in such a way that the US and our allies (including Europe) can outsource the production to poorer countries who give them their higher standard of living and consume, consume, consume, as they borrow, borrow, borrow to pay for their generous welfare state. Trump's pivot away from Europe threatens to undo all of that, and it's happening much, much faster than they ever envisioned. Europe's in for a rude awakening.
Europe is desperately trying to keep Trump aligned with Europe's security framework, and the centrist political parties in Europe stand to lose a lot if they can't keep Trump's America in Europe's corner. We're talking about the potential for a collapse of NATO and Europe as we've come to know it, and that would be a terrible development for many (most?) of the mainstream political parties and figures in Europe if this happened on their watch.
