Political map of North America & the Caribbean 15 October 1994 (New World Order): In 1990, Iraq invaded Kuwait (Iraq-Kuwait War) - the first major crisis of the post-Cold War world. Under US leadership, a global coalition which included members of the former Communist Bloc defeated the Iraqis (Operation Desert Storm), but the brief period of US-Soviet cooperation ended when the Soviet Union collapsed (Dissolution of the Soviet Union), leaving the United States as the world's sole remaining superpower.
