I think we all know why the EU was established.  But it's gone way past its remit by trying to force all these countries to meld together, whether they want to or not, in ways that don't necessarily benefit all the countries equally.   If the EU breaks up due to this, yeah, intra-European conflict indeed.  But it wouldn't have to happen if the EU technocrats weren't so damned determined to focus all power in their hands and compromised more with national sensibilities.

It also doesn't help that no one's forgotten what the Germans did to start the last major war - and that the Germans are now running the show.
