The Tattooed One
The big success of the EU is that after very many centuries of conflict and war in Europe, that prospect has all but disappeared, except perhsps in the Balkans.
Maybe I'm misguided in my history but I always thought one of the core intentions of integrating Europe was to minimise the chances of war, the "League of Nations" being the starting point way back in the 1920s(ish)?
The Balkans seem to have mostly sorted out their conflicts now, we're still left with some issues that could ignite because of separatist issues but they're relatively minimal, eg Catalonia, Basques, Scotland, Cornwall, Sealand....
