The Bush Doctrine is defined as "a collection of strategy principles, practical policy decisions, and a set of rationales and ideas for guiding United States foreign policy." Some of these had reemerged from the 1992 draft Wolfowitz Doctrine, which had been leaked and disavowed by the first Bush administration; Wolfowitz, as deputy secretary of defense, was at the center of the new Bush administration's strategic planning. Two main pillars are identified for the doctrine: 1.) preemptive strikes against potential enemies and 2.) promoting democratic regime change.
