We are the most powerful nation on earth because of our immense resources, geographic diversity, access to almost every major ocean and lack of powerful enemies on our border. Geography is destiny. Having the most arable land, having exploited the most oil, having access to the pacific, atlantic, arctic, etc and the ability to develop in peace due to having much weaker nations on our border is why we are a superpower.
The idea that we are the greatest nation because we have the best and brightest from around the world is simply not true. If it was true, our immigration policy would be based on IQ today.
China can't be a superpower because they are hemmed in by Russia to the north, India to the south, US/Japan/Korea alliance in the east and Iran/Central Asia/Middle East to the west.
If it is true that number of "geniuses" makes a nation the most powerful in the world, the most powerful nations would have been china and india. We know that's not the case. So your theory contradicts itself.
