Endless enlargement of the EU. 

I reverted some wierdly POV stuff about "some" people "fantasizing" about the EU endlessly enlarging.  I'm only mentioning it because it has a vague relevance because this is an article on world government and the EU is presented as an example of a larger supra-national regional governing body with some state powers.  If the editor who added those comments (anonymous, I seem to recall) wishes to have them included, they should identify who "some" people are, and cite sources, as well as attempt to phrase the contribution so as to flow with the article and be relevant.
