Book Description: Considering its long string of successes, it is curious that NATO has so many critics chanting the mantra of irrelevancy or decrying its post-Cold War initiatives. Paradoxically, pan-Europeanists seem quite willing to accept an ineffective security organization as long as it has a European label on it. Applying parochial protectionist practices on regional security may be irrevocable and certainly ruinous. In this monograph, Lieutenant Colonel Raymond Millen examines NATO’s extraordinary performance and incisive initiatives during the immediate post-Cold War years. While other security organizations and concepts have faded in importance and utility, NATO has made sweeping changes to remain relevant, and its unique enforcement mechanism means it has no security peer. Organizationally, NATO remains the greatest cost effective hedge against future threats and possesses the greatest potential for the full spectrum of conflict, to include crisis management. Notwithstanding its successes, NATO does need to conduct simple reforms, which, if implemented, will result in enormous cost savings and greater interoperability among new and old members. Allied bickering may result, but if the United States insists on their implementation, all members will fall in line. Lieutenant Colonel Millen scrutinizes the impact of enlargement on the Alliance, not only from a military but also a geopolitical perspective. He is quick to point out that, without the needed reforms, new members will bring more fat than muscle to the Alliance. However, the process of enlargement has served to harmonize Central and Eastern Europe with Western Europe in a remarkable manner. That achievement alone has made enlargement worthwhile. He goes beyond the next round of enlargement and makes a case for a reorientation of NATO enlargement towards the Middle East and North African regions. They may never receive the full security umbrella of NATO, but they can enjoy the shade. Lieutenant Colonel Millen provides a pragmatic roadmap for the future of NATO. The Strategic Studies Institute is pleased to offer this insightful and controversial monograph as a topic of debate among European security specialists.
