This important collection of essays brings together the work of prominent philosophers, political scientists, policy analysts, and defence consultants. It takes as its point of departure two central tendencies in current nuclear strategy: mutual assured destruction (MAD) and nuclear utilization target selections (NUTS). The essays examine and assess the arguments for these and other positions on the spectrum of policy options, and elaborate the implications of this analysis for strategic policy and for the further pursuit of research into SDI, and other matters.
