The complex question of the sovereignty of the Falkland Islands remains far from resolved, even after the military and political events that took place from April to June 1982. The first scholarly work of its kind, this broad and dispassionate study of the causes of the South Atlantic war between Britain and Argentina addresses the larger issues raised by the Falkland crisis and untangles a web of events and attitudes that stretch back over the past century. The book begins with a close evaluation of the two pivotal arguments: Argentina's stance that international law supports their historical right to the islands, and Britain's position that the length of their occupation of the Falklands, together with the principles of self-determination, legalized their de facto control. Gustafson then discusses how potential off-shore oil reserves, diplomacy, domestic politics, and the use of force entered into the sovereignty dispute; analyzes the effects of war on international relations; and considers possible future approaches to handling the dispute.
