Superpower goes behind the scenes of America's national security apparatus and military actions, and explores the dangers of government secrets and the US quest for global dominance through economic and military strategy. Through a series of interviews with historians, documentarians, academics, and other experts, such as Bill Blum, Chalmers Johnson, Michael Chossudovsky, Noam Chomsky, former Chief Economist for the US Department of Labor, Morgan Reynolds, and three-time Noble Peace Prize nominee, Kathy Kelly, the film examines key moments in America's history which inform US foreign policy actions.
