If I recall, it was formed in the 1950s. In the early 1970s it gained a lot of power. By the early 1990s, with the fall of the Soviet Union, they had another treaty to sign, which help set the France-Germany-Netherlands alliance. I don't see it as an end yet, even though there are a few country members that don't have equal representation on the EU. Finland, Norway, and Sweden get a lot of flack, but they mainly deal with their own problems and talk amongst themselves before putting forth a policy to be voted on.
Will the EU disband? Yes, but I say it will be another decade or two before we start to see it fall apart.
Furio, I suggest you keep an eye on Switzerland to see which way the wind is blowing. Right now that country is solid on almost everything including their economy.
