Hopefully by the time these 2 decades have passed, the EU and/or China will have become strong enough superpowers to keep the US in check, and we won't have to put up with any more of their senseless wars that don't seem to benefit anyone other than US corporations and the right-wing warhawks they're in league with.

Yes, I know, -1 Flamebait, but I promise you at least 90% of the world is wishing the same thing. Well, maybe not many will be wishing for China as the new global superpower, but personally I'd settle for that if it meant a balance of power. Anything to keep the US from flouting its military might around unchecked.
