From the thesis abstract: "The United States has lacked a definitive grand strategy since the end of the Cold War. In the wake of 9/11, the Bush Doctrine consisted of four fundamental tenets: do not discriminate between terrorists and nations that support them, engage emerging threats overseas, confront threats before they fully materialize, and advance liberty and hope as alternatives to repression and fear. Current U.S. foreign policy is consumed with crisis management rather than following a long-term game plan with a coherent set of objectives for managing the complex global environment. When viewed as a comprehensive framework for achieving U.S. objectives, the Bush Doctrine provides several critical and enduring concepts fundamental to a long-term strategy. In and of themselves, the Bush Doctrine's tenets cannot serve as the sole basis of foreign policy; but broadening their core objective from eradicating terrorism to addressing extremism and international instability imbue these tenets with an enduring utility for shaping American foreign policy. The realities of U.S. capabilities, the emerging operational environment, and the political aspirations of the nation's electorate codify certain elements of this doctrine as ideal and realistic strategic imperatives for the 21st century."
