Eh hard disagree there, the way I see it there is no more squabble between France and Poland than there is between Texas and California or between Spain and Romania compared to New york and Virginia. In fact, I would say we have LESS of it.

The only thing we need is to actually stop ignoring the forest for the tree and see that the world moved on beyond our petty local borders and we're lucky enough to have found a system where we're stronger together, to the point where we matter in the world and can't be ignored or pushed aside, while also protecting the core of each of our own cultural societies (langugage, history, ...), and only fools would let that go because they're too close minded to see it.
