How should NATO's military strategy and force posture in Western Europe be handled given today's changing relations between East and West? Five senior U.S. military officers spent a year exploring this issue at the Kennedy School of Harvard University. The book serves as a catalyst for discussion based on its proposal of replacing "forward defense" strategy with "resilient defense." "Resilient defense" articulates one way in which the United States and NATO can accommodate the pressures for reduced defense spending in the face of a reduced military threat.
