Historian Henry Maar's new book Freeze! The Grassroots Movement to Halt the Arms Race and End the Cold War examines the ways in which ordinary people confronted the horrors of nuclear war, with a specific focus on the extraordinary Nuclear Freeze campaign of the 1980s. In this conversation, Maar explains the roots of anti-nuclear activism in the United States, and tells us how Ronald Reagan's aggressive Cold War posturing (along with the nuclear apocalypse film The Day After) created an atmosphere of dread that sparked an unprecedented global movement.
