Whether the EU is a sleeping giant or not, I dont know. That depends on how they plan to use their military. I do know that the EU, if taken as if it were one state, is a super power. It is currently integrating the states more and more every day, with the intention of creating a united states of Europe. It would be a good thing if the governments were not so evil. But they will fall under China's influence economically and will be forced to be more passive in international affairs.
