I vote Moravscik. He may still be right about the origins of the EU, but he has been shilling the idea that the EU is the super-power of the future, as long as we slightly alter our ideas about what makes a super-power a little, for some time now. He had some pretty good stats to back it up, relying on things like GDP, etc.
That all takes a kick straight to the nads, though, with Britain out. The EU went to bed with a 16 Trillion dollar economy, and woke up with a 14 trillion dollar one. That is a major hit, and it likely won't stop until the fallout from Britain's withdrawal--which absolutely wasn't hedged against--shakes out over the next couple of years. If Britain walks it off and regains some of its sovereignty in the process, you could see more countries taking a pass on the "European Dream."
