Kuwait's invasion by Iraqi troops that began 2 August 1990 was met with international condemnation, and brought immediate economic sanctions against Iraq by members of the U.N. Security Council. U.S. President George H. W. Bush deployed U.S. forces into Saudi Arabia, and urged other countries to send their own forces to the scene. An array of nations joined the Coalition. The great majority of the Coalition's military forces were from the U.S., with Saudi Arabia, the United Kingdom and Egypt as leading contributors, in that order. Saudi Arabia paid around US$36 billion of the US$60 billion cost.
