SDI and US Foreign Policy

Showing how the development of space techonlogy could affect the system of deterrence, the authors consider the consequences for US foreign policy, alliance relations and strategic stability. In the first essay Dr. Tucker argues that a greater commitment to defensive systems would not substantially affect deterrence or extendeddeterrence. Dr. Liska suggests that a new offense-defensemix might enhance deterrenc because of the greater uncertainty of military outcomes. European responses to SDI are examined by Dr. Osgood, who maintains that the issue of defensive shields could only become the chief obstacle to establishing a more stable offense-defense weapons mix acceptable to the allies. In Dr. Calleo’s view the strategic dilemma of the United States can be improved only through a devolution of security responsibility.
