I'd add that the leading European nations, such as the UK, Germany and France, used to be global powers.

Power, soft and hard, depends in large part on pure economic capacity; that enables many things, including economic leverage, larger militaries, and high tech. I don't have the old numbers, but look at this list and imagine their relative power as individual nations before the rise of China and India:

But China and India likely will take two of the top three spots, along with the U.S., leaving those individual European powers far behind - $5 trillion economies in a world of $25 trillion superpowers (making a guess at future growth). They will be small fish among the sharks, no longer with a place at the table or influence on global affairs. A unified EU would be a fourth power, but that takes time, especially the political unification necessary to conduct foreign affairs (where the EU government has unified control of foreign policy - otherwise their words aren't backed up by the actual power). They are moving the wrong way.
