What we do, Strick, is to try to insert ourselves back into an international consensus. Even if it's no more effectual than the US government has been, it will at least have some degree of legitimacy with the international community. Then, we stop meddling in the affairs of other countries. In all of the cases where the US does intervene, it's always with some sort of expectation of profit (usually for the large corporate entities that helped get those in power in the US government where they are). The US doesn't ever do things for altruistic reasons.

I would suggest that the UN should be supported wholeheartedly by the US government, and that it be restructured so that all member nations have exactly the same rights within the organization as all the rest. No more special priveleges for the more powerful countries like the US. I think that would go a long way toward addressing the underlying problems. And I also think that the US should endorse, and become a member of the international court. We need to make this country accountable for what it does. Only then can we hope to really correct the problems that produce the symptom of "terrorism". (Including the state sponsored terrorism that the US has been engaging in for most of its existance.)
