As long as there is NATO and US troops in the EU, I don't see that this is happening (plus, all europeans need a nuclear arsenal under EU control).

I do not think tourism is an issue anywhere.

This is a possibility, but why would you discount other possibilities? The USA is saying a lot, but doing very little. Why are there still occupying troops in the EU? Didn't the USA announce how NATO is dead already? So why are there still troops?

I am very much not convinced that anything has really changed, aside from the rhetorics.
