The North Atlantic Treaty Organization has shaped Western security policy for more than seven decades. This book traces its founding in the aftermath of the Second World War, the political and military circumstances that led twelve nations to sign the Washington Treaty in 1949, and the organization's development through the Cold War and beyond. You will learn how NATO's institutions are structured, how decisions are made among member states, and how the alliance has adapted to new challenges such as enlargement, out of area operations, and evolving security threats. Written as a clear, accessible reference, it offers a straightforward account of the alliance's history and workings, suited for readers seeking a factual introduction to the subject.
