hmmmm I bet they told all the Euro-nations the same thing, we're only making it easier for you to go from country to country and then all of a sudden, next thing they knew, they were part of each other and no one voted on it; however, their vote after-the-fact in France certainly proved that they were not as on board as their leaders.
Uh, no. They've been after an intergrated Europe since the late 50's. They went through three decades of the European Community and another decade of the EU BEFORE the Euro came about.
Know you're history man, The EU and the Euro are two totally seperate issues. There have been several completely independent nations that have shared currencies in the past and there is NO reason to believe that will lead to any decrese in soverignity.
