This book discusses most recent developments in the area of US ballistic missile defense with an eye on its battlefield capacities since the Kuwait war, analyzed from the perspective of deterrence postures encompassing the key post-Cold War security challenges (Middle East, Far East, Eastern Europe). The analyzed cases of missile defense engagements included (after the Desert Storm), Operation Iraqi Freedom, Israeli operations against Hamas and Yemen war. The theoretical base of the book relied on the waves of deterrence theory since the early years of the nuclear age through the deployment of thermonuclear warheads, nuclear plenty and the late Cold War revisions of deterrence paradigms. The main body of the book is exploring the historical and probabilistic evidence on missile defense accuracy in various scenarios of its employment and differing layered short, medium and long range systems of the US counter-ballistic technologies. Historically, the missile defense investments since the early thermonuclear range were challenging the Mutual Assured Destruction paradigm. Notably, after partial marginalization of US long range missile defense concepts of the 1960s, seen as incompatible with 1972 Anti-ballistic missile treaty between the US and USSR, missile defense constructions were reinvigorated through Reagan's 1983 Strategic Defense Initiative, while post-1976 Patriot tactical air and missile defense were gradually winning arms contracts, as in the post Cold War age the value of extended deterrence grew. New post-Cold War missile defense investments included the Middle Eastern US allies, as well as Japan and South Korea threatened by DPRK nuclear and ballistic experiments. Importantly, the value of extended missile defense engagements became broader visible in the era of New Cold War between Russia and the West, when new Aegis Ashore bases in Romania and Poland proved the theater range missile defense capacity of new NATO members. Grzegorz Nycz, Ph.D. is adjunct professor at the Pedagogical University of Cracow's Institute of Political Science. He graduated from Jagiellonian University and Cracow University of Economics. Ryoichi Sasakawa Young Leaders Fellowship Fund Fellow 2007/2008. His research refers to U.S. security and foreign policy, with a special focus on nuclear deterrence and ballistic missile defense postures. His recent publications include monographs on strategic balance and U.S. national security policy and texts in periodicals related to ballistic missile defense investments, as well as U.S. military-political engagements in Eastern Europe, Middle East and East Asia in the time of the "New Cold War" between Russia and the West.
