What you have to realize is that that is true for us as well. India's 1.5 million active troops have no intentions whatsoever of marching into or colonizing any foreign country. Ten or fifteen years from now, India and China will both have more expeditionary warfare capability than all of Europe - but I am willing to bet my last penny, that neither country would want to wage war against Europe, far from wanting to vaporize it. Indians take pride in boasting that in the 5000 years of their history, they have never attacked another country (although that is not really true).
The mindset of Asian countries is quite different, on a national level. Don't judge by the racism and hatred displayed here by several posters - while it cannot be denied that such feelings exist, virtually nobody in India or China would want to destroy Europe, which is what you claimed would happen if these countries had Europe's power. (China already has the means to destroy Europe.)
I don't know about the Chinese, but the reason that so many Indians say hateful things about Europeans or whites is because of our history, of being colonised by the Europeans. I'm not justifying their hatred, simply explaining the reason.
