What kind of war is the war on terrorism? Ordinarily wars are fought against proper nouns—against Germany during the Second World War or against the Soviet Union during the cold war, for example.

Al Qaeda plus all other terrorists around the world? Al Qaeda plus all other terrorists plus all the countries in which the terrorists operate? In other words, just how good a job are the president and the administration doing, not just in prosecuting the war but in defining the objectives?
