Foreign policy strategy requires planning for multiple scenarios, imagining alternative futures, and facing up to risk. It also involves a constant, honest, rigorous assessment of whether existing policies are working - including how to adapt if they're not. Michael Oppenheimer shows how to conduct precisely these kind of assessments in his extremely useful new book, based on years of practical experience. The result is a work that should prove worthwhile to policymakers and analysts - indeed anyone interested in improving the quality of American foreign policy." -Colin Dueck, Associate Professor, George Mason University School of Policy, Government, and International Affairs.
