This book explores how rivalling discourses of American grand strategy reveal a fractured consensus of geopolitical identity and national security under President Obama. This conflict manifested in divergent elite visions of liberal hegemony, cooperative engagement and unilateral restraint. Georg L fflmann examines the identity conflict within the Washington foreign policy establishment, between elite insiders and outsiders, and how the 'Obama Doctrine' both confirmed a geopolitical vision of American exceptionalism and challenged established notions of US hegemony and world leadership.
