Pactomania is a term used to describe a period of treaty making by the United States during the Cold War. During the Presidency of Dwight D. Eisenhower, the United States (largely through the efforts of Secretary of State John Foster Dulles) formed alliances with 42 separate nations and treaty relations with nearly 100,[1] which observers described as "pactomania".[2] In more recent years, the term came to be used to refer to that historical period.[3]
