The atmosphere is nearly perfect for an EU resurgence. American workers potentially willing to leave is only one piece of it. You also have interest in drawing together as a continent against a new shared enemy. Hell even Germany is ready to drop their spending limitations to actually try to rise to the occasion.

I really wish they’d take it a step further and pump heavy investment into the region - and not just defense. Isn’t it exactly the right time to build European industries to replace the American ones they are no longer sure they can trust?
