There are several European countries who haven't always curtailed to the EC, there are several that never signed onto a universal constitution. Like I said I think the implementation of a lot of stuff coincided with them having gained more power than not, meaning having the greater control mechanism. But people can always be driven to rise to the occasion if backed into a corner they don't like and power in that regard can be reversed, it, as history has shown, sometimes ends up coming down to those willing to die for a cause.
