<p><strong>"Stephan Frühling's book examines the challenges of defense planning through an enlightening and insightful series of case studies. It provides scholars and policy-makers alike a rigorous and rich understanding of an important and under-examined field."</strong> – <em>Thomas G. Mahnken, Jerome E. Levy Chair of Economic Geography and National Security, U.S. Naval War College</em></p><p><strong>"Stephan Frühling has written by far the most insightful book to appear for many years on the ubiquitous and eternal challenges of defence planning. Few subjects as critically important as this have attracted so little disciplined and persuasive scholarly effort. Fruhling explains that defence planning is about the attempted management of risk in an unavoidably uncertain future, and that the risk management process is essentially always political. No matter how advanced the methods employed to try and reduce uncertainty, the inconvenient fact remains that because the future has yet to happen, thoroughly reliable knowledge about its dangers is unknowable now. Defence planning always is conducted in the context of an incurable ignorance about a future that has not occurred. Fruhling provides an exceptionally rigorous yet clear guide to the ways in which we can strive to conduct prudent defence planning despite our uncertainty: his is a landmark work that deserves a readership in many countries."</strong> – <em>Colin Gray, Professor of Politics and International Relations at Reading University, UK</em></p><p><strong>"Stephan Frühling has provided a thoughtful and thought-provoking work on defense planning at a time when the Pentagon needs it most. <br />With the United States planning a major reorientation of its defense posture toward Asia following over a decade of war in Iraq and Afghanistan, Pentagon planners are once again brushing up on strategy. They would do well to include Stephan Frühling's <em>Defense Planning and Uncertainty</em> among their readings."</strong> – <em>Andrew Krepinevich, </em><em>President of the Center for Strategic and Budgetary Assessments (CSBA), USA</em></p>
