This is a book on how to think - strategically - about foreign policy, particularly American foreign policy. Strategy is about the relationship, in thought and action, between ends and means; it is about the application of resources to achieve objectives. The book discusses the national interest as a concept in strategic logic and describes how to select objectives that will take advantage of opportunities to promote interests while protecting them against threats. It also discusses national power and influence, as well as the political, informational, economic, and military instruments of state power. In addition, the book looks at the contemporary international environment for foreign affairs strategy, as well as the domestic context in which it must be formulated and executed. Based on a graphic model that illustrates strategic logic, the book uses examples from recent American statecraft. It ends with an extended critique of current American foreign policy and a detailed outline of an alternative strategy that is better suited to the problems of the 21st century.
