The six-week war, telecast around the world from start to finish (February-April 1991), was significant because it was the first major international crisis to take place in the post-Cold War era. The United Nations proved to be effective in organizing the coalition against aggressor Iraq. Leading members of the coalition included Egypt, France, Great Britain, Saudi Arabia, Syria, and the United States. The conflict also tested the ability of the United States and the Soviet Union (then still in existence as such) to cooperate in world affairs.
