The Second Persian Gulf War,. also known as the Iraq War, Mar.–Apr., 2003, was a largely U.S.-British invasion of Iraq. In many ways the final, delayed campaign of the First Persian Gulf War, it arose in part because the Iraqi government failed to cooperate fully with UN weapons inspections in the years following the first conflict.
The election of George W. Bush to the U.S. presidency returned to government many officials from his father's administration who had favored removing Saddam Hussein from power in the first war. After the Sept. 11, 2001, attacks on the World Trade Center and Pentagon, the United States moved toward a doctrine of first-strike, pre-emptive war to eliminate threats to national security. As early as Oct., 2001, U.S. Defense Secretary Rumsfeld publicly suggested that military action against Iraq was possible, and in November President Bush asked Rumsfeld to undertake a war-plan review. In Jan., 2002, President Bush accused Iraq. along with North Korea and Iran, as being part of “an axis of evil,” and with the Taliban forced from power in Afghanistan in early 2002, the administration's attention turned to Iraq.
Accusing Iraq of failing to abide by the terms of the 1991 cease-fire (by developing and possessing weapons of mass destruction and by refusing to cooperate with UN weapons inspections) and of supporting terrorism, the president and other officials suggested that the “war on terrorism” might be expanded to include Iraq and became more forceful in their denunciations of Iraq for resisting UN arms inspections, called for “regime change” in Iraq, and leaked news of military planning for war. President Bush also called on the United Nations to act forcefully against Iraq or risk becoming “irrelevant.” As a result, Iraq announced in Sept., 2002, that UN inspectors could return, but Iraqi slowness to agree on inspection terms and U.S. insistence on stricter conditions for Iraqi compliance stalled the inspectors' return.
In October, Congress approved the use of force against Iraq, and in November the Security Council passed a resolution offering Iraq a “final opportunity” to cooperate on arms inspections. A strict inspections timetable was established, and active Iraqi compliance insisted on. Inspections resumed in late November. A December declaration by Iraq that it had no weapons of mass destruction was generally regarded as incomplete and uninformative, but by Jan., 2003, UN inspectors had found no evidence of forbidden weapons programs. However, they also indicated that Iraq was not actively cooperating with their efforts to determine if previously known or suspected weapons had been destroyed and weapons programs had been ended.
Despite much international opposition, including increasingly rancorous objections from France, Germany, and Russia, the United States and Britain continued their military buildup in areas near Iraq, insisting that Iraq was hiding weapons of mass destruction. Turkey, which the allies hoped to use as a base for a northern front in Iraq, refused to allow use of its territory, but most Anglo-American forces were in place in Kuwait and other locations by March.
