The early 1980s were a tense time. The nuclear arms race was escalating, Reagan administration officials bragged about winning a nuclear war, and superpower diplomatic relations were at a new low. Nuclear war was a real possibility and antinuclear activism surged. By 1982 the Nuclear Freeze campaign had become the largest peace movement in American history. In support, celebrities, authors, publishers, and filmmakers saturated popular culture with critiques of Reagan’s arms buildup, which threatened to turn public opinion against the president. Alarmed, the Reagan administration worked to co-opt the rhetoric of the nuclear freeze and contain antinuclear activism. Recently declassified White House memoranda reveal a concerted campaign to defeat activists’ efforts. In this book, William M. Knoblauch examines these new sources, as well as the influence of notable personalities like Carl Sagan and popular culture such as the film The Day After, to demonstrate how cultural activism ultimately influenced the administration’s shift in rhetoric and, in time, its stance on the arms race.
