The US-Japan alliance has contributed significantly towards the development of the Japanese security strategy. The Evolution of the US-Japan Alliance explores developments in the alliance between the US and Japan and analyzes the transformation of the Japanese security strategy from 1960 to 2013. It also describes the rise and the decline of Japanese pacifism and of the Yoshida Doctrine, the post war security strategy. Moreover, this book highlights how the end of the Cold War forced Japan to rethink its security strategy and post war pacifism. Japan has abandoned its identity of "peaceful nation , turning itself into a "normal national , drawing closer to the United States.
