...the War on Terror is in fact a war against Islam. After all, this was never conceived of as a war against terror per se. If it were, it would have included the Basque separatists in Spain, the Christian insurgency in East Timor, the Hindu/Marxist Tamil Tigers in Sri Lanka, the Maoist rebels in eastern India, the Jewish Kach and Kahane underground in Israel, the Irish Republican Army, the Sikh separatists in the Punjab, the Marxist Mujahadin-e khalq, the Kurdish PKK, and so on. Rather, this is a war against a particular brand of terrorism: that employed exclusively by Islamic entities, which is why the enemy in this ideological conflict gradually and systematically expanded to include not just the persons who attacked America on September 11, 2001, and the organisations that supported them, but also an ever-widening conspiracy of disparate groups such as Hamas in Palestine, Hizbullah in Lebanon, the Muslim Brotherhood in Egypt, the clerical regime in Iran, the Sunni insurgency in Iraq, the Chechen rebels, the Kashmiri militants, the Taliban, and any other organisation that declares itself Muslim and employs terrorism as a tactic.
