First of all, Mr. Anomymous IP, the EU is not a unified entity. The EU lacks a unified foreign policy. You state that "For istance if Usa attack EU the same Usa would disappear for nuclear answer!" I don't know where to begin. This isn't intelligent of even coherent. Second, you don't seem to realize that the EU is not a single entity that the U.S. could declare war upon. Furhermore, your scenario of the US and EU going to war is ludicrous. Also, although the EU as a whole has a slightly larger economy than the United States, an essential aspect of a single economy is a unified currency. The Eurozone itself has a smaller economy than the United States. America and Europe have been joined under NATO, as well as steadfast allies. In addition, though you claim "a lot af people" claim the US isn't a superpower, here at Wikipedia, we only use reliable, academic sources, not POV and original research. The next time you spout off your unsubstantiated theories, bring solid, academic proof of the claimns you make.
