One in a series of booklets whose purpose is to stimulate greater and more effective understanding of world affairs among Americans, this six-chapter report examines the North Atlantic Treaty Organization's (NATO) first 35 years and probes the extent to which the alliance can find common ground on the perennial issues of military doctrine, burden-sharing, global strategy, and international economics. "The Balance Sheet" outlines NATO's development. "The Security of the North Atlantic Area" looks at technology and nuclear strategies. "Grand Strategy?" identifies the areas in dealing with the Soviet threat. "The Third World" examines NATO responses outside its scope. "Economic Relations" looks at the severe economic problems of NATO. "The Future" considers the alliance's future. The "Talking It Over" section offers questions for students and discussion groups. The report includes maps, charts, and suggested readings. (TRS)
