European Union = Next United States?

After checking out this Libson treaty, it seems like the EU is going to become one major country. Their form of government seems to be a bit similar to the American government. Probably not that close since our US government is fucking weird, but close enough.

Ireland just passed their support for the treaty. What does Europe becoming on country mean for the rest of the world?

"The man of the future will be of mixed race. Today's races and classes will gradually disappear owing to the vanishing of space, time, and prejudice. The Eurasian-Negroid race of the future, similar in its appearance to the Ancient Egyptians, will replace the diversity of peoples with a diversity of individuals."

- Count Richard Nikolaus von Coudenhove-Kalergi, one of the most important people behind the european union.
