Bush presided over the invasion of Panama and the Gulf War, ending the Iraqi occupation of Kuwait in the latter conflict. Though the agreement was not ratified until after he left office, Bush negotiated and signed the North American Free Trade Agreement (NAFTA), which created a trade bloc consisting of the United States, Canada, and Mexico. Domestically, Bush reneged on a 1988 campaign promise by enacting legislation to raise taxes with the justification of reducing the budget deficit. He also championed and signed three pieces of bipartisan legislation, the Americans with Disabilities Act of 1990, Immigration Act of 1990 and the Clean Air Act Amendments of 1990. He also successfully appointed David Souter and Clarence Thomas to the Supreme Court. Bush lost the 1992 presidential election to Democrat Bill Clinton following an economic recession, his turnaround on his tax promise, and the decreased emphasis of foreign policy in a post–Cold War political climate.[3]
After leaving office in 1993, Bush was active in humanitarian activities, often working alongside Clinton, his former opponent.
