This is the first introduction to the United Nation's activities during the Cold War period. It combines a history of the UN with a broader account of east-west diplomacy during the Cold War and after. Norrie MacQueen begins by looking at the formation, structure and functions of the UN. Then, within a chronological framework, he assesses its contribution to international security from the emergence of the UN's peacekeeping role in 1945-56 right through to UN operations in the 1990s in Angola, Somalia and Bosnia.
