Look around yourself in your country. Are people good enough there and no "occupy wall street" actions taking place?
I know how the things are in the helped to be "developed" countries, and one from one of those.
But who wins the global world is yet to be seen.
Give me an example where one countrie does something bad to a nother where they have no choise.
Edit
Typical example: Greek was not forced to do Austerity they do so because they want to get money. The could, and should (in my opinion) have devolted long ago, like Island there much better of now.
There might be some few good cases but the greater part of history just serves my pessimistic view. All the empires claimed to help less developed nations to become "better". Only for some strange reason the latter didn't want this help until persuaded with military force.
