The Apathy of Empire reveals just how significant Cambodia was to U.S. policy in Indochina during the Vietnam War, broadening the lens to include more than the often-cited incursion in 1970 or the illegal bombing after the Paris Peace Accords in 1973. This theoretically informed and thoroughly documented case study argues that U.S. military intervention in Cambodia revealed America's efforts to construct a hegemonic spatial world order.

James Tyner documents the shift of America's post-1945 focus from national defense to national security. He demonstrates that America's expansionist policies abroad, often bolstered by military power, were not so much about occupying territory but instead constituted the construction of a new normal for the exercise of state power. And yet America's grand strategy was one of contradiction: to build a sovereign state (South Vietnam) based on democratic liberalism, it was necessary to protect its boundaries—in effect, to isolate it—through both covert and overt operations in violation of Cambodia's sovereignty.

Questioning reductionist geopolitical understandings of states as central or peripheral, Tyner explores this paradox to rethink the formulation of the Cambodian war as sideshow, revealing it instead as a crucial site for the formation of this new normal.
