We believe the ICC undermines the role of the United Nations Security Council in maintaining international peace and security.
The UN has never maintained international peace and security and never will. Nor has the US maintained peace and security and those who think that the primary role of any "superpower" or global government is to maintain peace and security should have their head examined.
Is the UN the best way to do that, I don't think so. But we de need some sort of tribunal type commission in order to have healthy relationships with all the other powerful nations. I guess, if UN would just do what it was originally intended to do, it would be for the best.
