During the debate, Congressman Paul commented that America's history of interventionism in the Middle East has led to an unpopular view of the U.S. in Middle Eastern countries, and argued that the CIA's removal of Iranian leader Mohammed Mosaddeq in Operation Ajax, the Iraq War and the bombing of Iraq in the 1990s had led to increasing anti-American sentiment in the Middle East and promoted terrorism. When the moderator asked if Paul was suggesting that the US had "invited" the 9/11 attacks, Paul argued with fellow candidate Rudy Giuliani, who responded to Paul's suggestion that the U.S. pay attention to the underlying causes of terrorism by saying "I don't think I've heard that before, and I've heard some pretty absurd explanations for September 11. And I would ask the congressman to withdraw that comment and tell us that he didn't really mean that." Paul responded that terrorists were the result of "blowback" from poor foreign policy, and that they "don't come here to attack us because we're rich and we're free, they come and attack us because we're over there."
