American Science: Addicted to Pentagon Cash?

An anonymous submitter writes: "In totalitarian states the military can compel scientists to perform research for weapons systems. That's not true in the United States, yet American scientists who refuse military work are exceedingly rare today. This may be in part because scientists, like most other citizens, agree that the U.S. is facing dangerous foes. But some dissidents argue the cause is more likely that Pentagon cash has become an addiction that scientists rationalize by working on 'dual use' technologies -- radar that maps planets and guides missiles; robots that peer through smoke in apartment fires to rescue victims, and through battlefield smoke to find human targets."
