Book excerpt: "This Note describes the origins, goals and tactics of the anti-nuclear-weapons and anti-nuclear-energy protest movements in the United States; characterizes American anti-nuclear protest activities of the past several years, and compares them with analogous protests abroad; and suggests some approaches for using this information to assess the potential for violent actions against U.S. nuclear-energy and nuclear-weapons installations. Appendixes include brief histories of the Clamshell Alliance and the Livermore Action Group, and a chronology of anti-nuclear protests from 1977 to 1983"--Rand abstracts.
