You are probably right, but the EU itself is a great power if you consider the combined resources of all member-states. I am thankful that the US is always an ally of Western Europe but it has to be remembered that the EU have a vital part to play in the resolution of this crisis. Some people in the US state dept. *cough* Victoria Nuland *cough* need to realise this.
I don't discredit the might of the EU, but its lack of constitutional sovereignty, IMHO, will always prevent it from being a true superpower. The member states, combined, are extremely powerful, but when shove comes to punch, is there a credible guarantee that that power can be mustered? If there's any disagreement at all on a course of action, Germany, France, or the UK can dig in its heels and there's really not anything the EU can do about it. Power is nothing without credibility.
