Not the Nazis, the Third Reich. There was more to it than the political party in control. The entirety of German industry/finance was an imbedded part. I find it an error of classification ot narrow down your assessment of that version of German empire as "the Nazis."
Mel, I admit to conflating the "Euro monetary union" with the EU, but you would not have the former without the forms of the latter.
So I was being a bit sloppy.
The EU is far from perfect, but in its defence I'd say it is probably the reason why its members have not had a war since 1945.
Horse****. You had forty years of occupying powers in central Europe keeping a lid on such things, as well as a tangible threat/concern to unite against, which was the malevolant power to the East. Your EU/continental security and stability was a direct result of occupation and support from the US of A and to a lesser extend, the French and the Brits.
