In a statement issued on February 23, 1998, titled Al-Qaeda’s Declaration of War Against Americans, Osama bin Laden wrote: “[I]n compliance with Allah’s order, we hereby issue the following decree to all Muslims: The ruling to kill the Americans and their allies–civilians and military–is an individual obligation incumbent upon every Muslim who can do it and in any country–this until the Aqsa Mosque [Jerusalem] and the Holy Mosque [Mecca] are liberated from their grip, and until their armies withdraw from all the lands of Islam, defeated, shattered, and unable to threaten any Muslim.’ ”
