WHY WE FIGHT is an unflinching look at the anatomy of American war-making. Granted unparalleled Pentagon access, the film launches a nonpartisan inquiry into the forces - political, economic, and ideological - that drive America to fight. Featuring John McCain, Gore Vidal, Richard Perle and others, WHY WE FIGHT explores a half-century of U.S. foreign policy from World War II to the Iraq War, revealing how political and corporate interests have become alarmingly entangled in the business of war.
