“On September 16, 2001, [President] Bush asserted: ‘This crusade, this war on terrorism, is going to take a while.’ This statement created much controversy, and since then the president has dropped ‘crusade’ from his rhetoric. …Muslims…have understandably developed a great aversion to the word [crusade] and its history; and al-Qaeda often points to President Bush’s remark as evidence that the war on terror is essentially a war on all Islam waged by malicious Christians.”
