This introduction to the book offers readers a gateway into the world of grand strategy, exploring its historical roots and its significant influence on the United States (U.S.) foreign policy. It begins by reflecting on the enduring tradition of conflict-driven warfare and traces the evolution of strategic thought from tactical maneuvers on the battlefield to comprehensive, long-term planning at the strategic level. The book argues that grand strategy, with its four key elements—unilateral action, multilateral action, military intervention, and military non-intervention—lies at the heart of statecraft, shaping the destinies of nations. Central to this narrative is the U.S., a nation whose grand strategies have captured global attention since its inception. Through a nuanced exploration of grand strategy, this introduction sets the stage for a profound understanding of Obama’s grand strategy in the Middle East and its profound implications for U.S. foreign policy.
