I'm talking economically, which is the major measure of power. Depending on which figures you use, the EU is either the largest GDP on earth, or a close second behind America. The political union intends to move closer towards integration, including militarily in the face of a resurgent and aggressive Russia. I can totally understand people resisting the idea of seeing the EU as a superpower or potential superpower as the countries within are still sovereign, and their militaries independent. It's certainly not laughable to be talking in those terms though. The wealth and potential power of Europe working as a union is considerable, and may prove an extremely important counterweight to US-Russian-Chinese power in future.
