Al Qaeda and ISIL and groups like it are desperate for legitimacy. They try to portray themselves as religious leaders — holy warriors in defense of Islam. That’s why ISIL presumes to declare itself the “Islamic State.” And they propagate the notion that America — and the West, generally — is at war with Islam. That’s how they recruit. That’s how they try to radicalize young people. We must never accept the premise that they put forward, because it is a lie. Nor should we grant these terrorists the religious legitimacy that they seek. They are not religious leaders — they’re terrorists. (Applause.) And we are not at war with Islam. We are at war with people who have perverted Islam. (Applause.)
