How the world responded to Kuwait's needs...History and Society, Persian Gulf War, Britannica
Over the following months the U.S. military carried out its largest overseas deployment since World War II. By mid-November the U.S. had more than 240,000 troops in the Gulf and another 200,000 on the way, and the United Kingdom had sent more than 25,000, Egypt 20,000, and France 5,500. Some 25 other countries, including Canada, Syria, Bangladesh, and Morocco, had committed troops and weapons to the military buildup that was designated Operation Desert Shield. On November 29, 1990, the UN Security Council passed Resolution 678 by a vote of 12 to 2, sanctioning the use of force if the Iraqis had not left Kuwait by January 15, 1991. Only Cuba and Yemen voted against the resolution, with China abstaining. This was the first UN authorization of the use of force since 1950, when the Security Council approved military action against North Korea after its unprovoked attack on South Korea. With this resolution in place, the U.S. offered to engage in a dialogue with Saddam to extend the possibility of a peaceful settlement based on a timely Iraqi withdrawal. unquote
Think there were more that contributed. Hussein had his eyes on Saudi Arabia, who helped as much as anyone else.
