Indeed. And even if we opt for a USE, there are different models for such a USE: a centralized ideal French-style, a federalized one German-style, ... and economically, a more socialist-authoritarian one French/German-style, a more capitalist-liberal one British/Eastern-European-style. Trying to find a common ground and to converge towards a model that is acceptable by all member states is nearly impossible. Just look at the total fiasco that the single currency Euro turned out to be: due to different financial philosophies between North and South, the whole Euro-Zone is shattered, and their central bank is printing billions of Euros like there's no tomorrow, heading right towards a super crash. Frankly, the anti-USE in the UK have won, and it pains me to say: they were right. I too was hoping for some kind of USE, but I grew disillusioned. I think right now that the EU should be rebooted and rebuilt (much more carefully) from scratch. On the second try, things could improve. As it stands now, keeping working on it will only add more misery to an utterly broken design, IMHO.
