Globalization offered the model for this. When the economy is globally linked there is more pressure for stability than conflict. I think that theory still holds. The fallout of the last 10 years is that the distribution of the wealth created in that system has not been even at all, and we are seeing huge wealth gaps. Jobs were redistributed to poorer nations and lost in a lot of wealthier markets.

If nations can solve wealth and job distribution under globalization then I think we return back to peaceful times. The current problems stem from people getting left out and then voting in leaders who do not understand diplomacy or the global market at all.
