In a groundbreaking contribution to the international relations literature, Kromer examines the historical experience of NATO with new weapons technologies and analyzes their effect on alliance stability. Concentrating specifically on new, innovative, radically different technologies--rather than on modifications or upgrades to existing weapons systems--Kromer uses a focused comparison methodology to develop his arguments. His study takes the form of detailed case studies and comparative analysis of two particular new weapons technologies: tactical nuclear weapons and precision guided munitions. For each, Kromer explores the political effects and implications of the new technology, an area of study that has received little attention until now.
