Should the United States invade Iraq and depose Saddam Hussein? Over the past few months, advocates of war have advanced a number of reasons why toppling Saddam is desirable. He is a bloodthirsty tyrant. He has defied the United Nations on numerous occasions. He has backed terrorists in the past. Removing him will reinforce respect for American power and spark democratic reform in the Middle East. If you're looking for a reason to support a war, in short, there are lenty from which to choose.

George W. Bush certainly did not expect to be a war president. In his private sector career and as Governor of Texas he had seldom traveled abroad, and he did not demonstrate much interest in international affairs. In his campaign for the presidency he expressed skepticism about foreign entanglements and a disdain for “nation building.” Yet events conspired to make war the central concern of his presidency; after the terrorist attack on the United States in September 2001, Bush saw the war on terrorism as the primary mission of his presidency. “I'm here for a reason, and this [the war on terrorism] is going to be how we're to be judged.”1 Soon thereafter he decided that the U.S. should conduct a campaign for regime change in Iraq, by military means, if necessary.
