>>>>I don't think it was presented that way originally. I recall reading and then later discussions here on the UT (or I think it was here on the UT) that the goal of the EU was to eventually become a world power equal to the U.S. politically, economically, and militarily. There were arguments that no, it was only economic and nothing else otherwise no country would agree to join. Not that it would be a bad thing necessarily, but it would have the potential of being a bad thing and not just for us but for the citizens of each of the member countries. No more autonomy when that all comes to pass. What then happens with the UN? Do we have the UN, the EU, NATO, et al...?
