Not to be too simplistic, but my take is that once the Soviet Union fell we were the undisputed "leader of the world." And with that designation we decided that we had the wherewithal to social engineer. What I fail to understand is, if our own infrastructure is crumbling and our populace has better things to do than be civic minded, why do we think we have it all figured out? And as I posted before, the best thing we could - and still can - do is determine who/where the perpetrators are, get the state where they are to act responsibly or if they refuse (see Afghanistan) you simple turn them into the Stone Ages. Now you won't necessarily get closure in that area but you have sent the unmistakable message to the rest of the world that you fail in your jurisprudence at your own risk. And I am sure that quite a few "precocious" states will suddenly get religion.
