Michael A. McFaul - The United Nations and its Security Council have never been the ultimate authority in deciding issues of war and peace. During the Cold War, the Security Council was so deeply divided that it rarely voted on anything meaningful. After the Cold War, the U.N.'s role expanded but its effect on world affairs remained limited. For example, the Clinton administration did not seek U.N. approval of the NATO-led war against Serbia. Nor did the United States and Great Britain seek U.N. approval for their last major bombing campaign against Iraq, in 1998.
