BTW Czechoslovakia split to Czech Republic and Slovakia a few years after the iron curtain fell. It was a relatively painless process and probably it led to much less tensions later on. It's something like 10 and 5 million people. Probably could split even further and I'd be very curious where is the optimum for 21st century.

EU? I wish it was just a fee trade union, nothing more. At this point it feels more like a government for governments, where my vote means absolutely nothing.
