There's a theory that after war, the people want to make it never happen again. Then they get older and die, and the fourth or so generation lacks all of that experience or motivation, and so someone is bound to start a war because people don't learn from the past. The EU itself is likely still very far from starting that war. China and its superiority complex seems much more likely if they can find someone willing to stand up to them. Or maybe Russia is going to overstep its boundaries for real sometime. Either way we're probably close to our 80 or so years of "Western" (relative) peace, certainly fear and populism are not helping to avoid that path.
