In 1988 Bush won the Republican nomination for President and, with Senator Dan Quayle of Indiana as his running mate, he defeated Massachusetts Governor Michael Dukakis in the general election. Bush faced a dramatically changing world, as the Cold War ended after 40 bitter years, the Communist empire broke up, and the Berlin Wall fell. The Soviet Union ceased to exist; and reformist President Mikhail Gorbachev, whom Bush had supported, resigned. While Bush hailed the march of democracy, he insisted on restraint in U. S. policy toward the group of new nations. In other areas of foreign policy, President Bush sent American troops into Panama to overthrow the corrupt regime of General Manuel Noriega, who was threatening the security of the canal and the Americans living there. Noriega was brought to the United States for trial as a drug trafficker. Bush's greatest test came when Iraqi President Saddam Hussein invaded Kuwait, then threatened to move into Saudi Arabia. Vowing to free Kuwait, Bush rallied the United Nations, the U. S. people, and Congress and sent 425,000 American troops. They were joined by 118,000 troops from allied nations. After weeks of air and missile bombardment, the 100-hour land battle dubbed Desert Storm routed Iraq's million-man army. Despite unprecedented popularity from this military and diplomatic triumph, Bush was unable to withstand discontent at home from a faltering economy, rising violence in inner cities, and continued high deficit spending. In 1992 he lost his bid for reelection to Democrat William Clinton. --------------------------------------------------------------------------------.
