Which of the following films was designated as foreign political propaganda by the U.S. Department of Justice?

Directed by Terri Nash, "If You Love This Planet" is a 1982 short documentary film recording a lecture given to SUNY Plattsburgh students by physician and anti-nuclear activist Dr. Helen Caldicott, founding President of Physicians for Social Responsibility. In the film, Dr. Caldicott outlines the effects of detonating a single twenty-megaton bomb, and traces the development of atomic weapons from the devastating bombs of the 1940s to the even more dangerous, apocalyptic weapons of today. "If You Love This Planet" provides an urgent warning that time is running out – that unless we shake off our indifference and work to prevent nuclear war, we stand a slim chance of surviving. Her message is clear: disarmament cannot be postponed. Archival footage of the bombing of Hiroshima and images of its survivors seven months after the attack heighten the urgency of her message.

Released during the first term of the Reagan administration and at the height of Cold War nuclear tensions between the United States and the Soviet Union, "If You Love This Planet" was officially designated as "foreign political propaganda" by the U.S. Department of Justice and suppressed in the United States. The subsequent uproar over that action gave the film a publicity boost; it went on to win the 1982 Academy Award for Documentary Short Subject.
