Even if the insanity stopped right this second, it's likely that the EU will be actively working to step out of the US's economic and military shadow in the next couple decades. For anyone not in tech, most of the EU is already better than most of the US. The same is also true for many people
in tech (most outside NYC/SF/Seattle).
Also, Canada. They're likely to withstand global warming better than most of the world, and would be comparatively easy to adapt to. If I didn't own a house, I'd already be working to move there, though I have recent ancestry that makes it a relatively more appealing option.
