The Defenders

No weapon has ever been frightful enough to put a stop to war-perhaps because we never before had any that though for themselves!"The Defenders" is Philip K. Dick's classic science fiction short story about a nuclear war between the United States and the Soviet Union, in which both sides have taken refuge in underground bunkers, leaving the fighting to intelligent robots on the supposedly radioactive, toxic surface. The weapons of war created by both sides may, however, be more intelligent than their creators realized.
