This book is comprised of essays by nationally recognized scholars and public figures who urge a reassessment of the impact of the nuclear winter hypothesis on current ideas of nuclear deterrence, limited nuclear war, and war fighting doctrines. It provides a timely discussion of the policy implications of the possible effects of nuclear war and creates a dialogue between those who believe that established deterrence policies are adequate and those arguing for a radical reconstruction of those policies. The book also addresses issues touching on the politics of prevention, identifying policies that should be adopted to prevent nuclear war, and the concerned citizens' role in this process.
