Before the devastating deployment of atomic weaponry ended World War II, the terrifying prospect of germ warfare loomed as word reached President Roosevelt that the Axis powers were developing biological weaponry. As the president gave U.S. scientists the go-ahead to pursue similar weapons, dire moral questions emerged. This "American Experience" program covers the unsettling arms race of the 1940s and '50s. 60 min. Soundtrack: English Dolby Digital stereo.
