An exception to this principle is when an intelligence agency's estimate seems to serve its bureaucratic interests. The estimate might be right, but it shouldn't be given extra credence on the basis of the agency's expertise; in this instance, it should be accorded extra doubt. For instance, in the 1950s, Air Force Intelligence estimated that the Soviet Union would soon deploy hundreds of intercontinental ballistic missiles. If taken as truth, this estimate would compel the president to deploy hundreds of American ICBMs—which were funded by the Air Force. Similarly, today, if Air Force Intelligence makes fearful claims of China's military, one motive might be to make a case for the Air Force's F-22 aircraft.
