I think the EU certainly helped a lot by trade and free movement of people. It's a lot harder to make people from another country into demons if you've met them and shared a bottle of wine with some of their (almost inevitably from a UK perspective, better) food. Not impossible - but much harder.

I think we've had proxy wars by major powers going back millenia - I don't think that's such a strange situation for Europe compared to free movement and cheap flights.
