Puzzles me, that nobody has mentioned this yet: EU states are nation states, US states are not. The EU is not a nation, the US are. EU states have much more sovereignty than US states written inside laws, but more importantly, through support of their people. This is why there is a Euro crisis and why Brexit happened: The unification of Europe is a beautiful idea and I personally hope it will recover, but while subsets of it were considered as one nation at some point (Austria, Germany etc.) the EU as a whole simply never was and never will be.
