By the time the EU stops squabbling and gets down to serious business, the US will have come up with cold fusion or energy from dandelions, making EU's oil fields irrelevant. They will never achieve parity with the US in the matter of military hardware/expertise. Their only hope is to tie us down like Gulliver...to the UN. Which won't happen.
Hmm, the EU is rather protectionist and they haven't sent off nearly as much industry to China and India. Further if our dollar keeps falling we will have a hard time attracting scientists from all over and oil will become extremely expensive with sky rocketing inflation, that will grind us down. Just the breathing room the EU needs to morph the rest of the way to the Reich. Hitler was impatient. The new Reich masters aren't.
