The author examines three features of the war on terrorism as currently defined and conducted: (1) the administration's postulation of the terrorist threat, (2) the scope and feasibility of U.S. war aims, and (3) the war's political, fiscal, and military sustainability. He believes that the war on terrorism--as opposed to the campaign against al-Qaeda-- lacks strategic clarity, embraces unrealistic objectives, andmay not be sustainable over the long haul. He calls for downsizing the scope of the war on terrorism to reflect concrete U.S. security interests and the limits of American military power.Abstract: The author examines three features of the war on terrorism as currently defined and conducted: (1) the administration's postulation of the terrorist threat, (2) the scope and feasibility of U.S. war aims, and (3) the war's political, fiscal, and military sustainability.
