"It is no secret that the US variously pulls away from the United Nations and embraces it as a significant venue for policy initiatives. But what explains this dramatic inconsistency? What is the logic of US multilateralism? Alynna Lyon explores the puzzling waxing and waning of US support for the UN, tracing events, actions, and decisions from the end of World War I to the present. Lyon weaves together a consideration of international context, UN institutional dynamics, and US domestic politics to conceptualize and explain the trials and tribulations of the US-UN relationship. In the process, she tells the story of the progression of the US from a country committed to internationalism to one full of dysfunctional partisanship, ideological underpinnings, and domestic power struggles that undermine its capacities to cooperate on a global scale." -- Publisher's description
