It's also my opinion that the current, 'United States of Europe' model for the EU will not last 25 years.
That was my opinion... 25 years ago :-)
Looking at the breakup of the Soviet Union, the decentralization and globalisation of the economy and other factors, I wrote an essay about how the overall forces were against the EU. And yet... 25 years later, just one country has peeled off and several have joined since I predicted the forthcoming decline of the EU.
So much for my abilities as a prognosticator. The bad part is that I actually wrote this down and a couple of years ago, looking through old files, found the essay on my hard drive. So I learned my lesson: never write down your predictions until *after* they have come to pass. You're accuracy goes WAY up when you do it that way ;-)
