We are killing people in acts of war across Central Asia, the Middle East and Africa and expect to kill quite a few more. We are fighting a battle first to contain and then to defeat a vicious ideology of murder and hate that masks itself as religious zeal. We are fighting this war both at home and abroad, and there is not an inhabited continent anywhere on Planet Earth where this threat is not a serious concern. All Muslims are not our enemies — far from it, and many of our most important allies and associates are decent, pious, enlightened Muslims who loathe the hate-spewing murderers as much as anybody else — but all of our enemies claim to be fighting in the name of Islam.
