The defense cooperation of United States of America and Japan

The Japanese-American defense cooperation is the cornerstone of the regional security structure of Asia and the Pacific. This cooperation was established in accordance with the Mutual Security Treaty signed in 1960, which focused on joint deterrence and confronting regional and global challenges. With the end of the Cold War, the collapse of the Soviet Union, and the growing Japanese sense of security weakness. Russia, which has not signed a peace treaty with Japan, still controls the Kuril Islands, in addition to anxiety and tension towards North Korea, its nuclear and missile capabilities, its nuclear tests, and the continuing threat to use nuclear weapons. China has regional ambitions, especially in the East China Sea, and the ambiguity surrounding its military capabilities, as well as other problems that abound in the continent, which require a role that adapts to these changes, takes into account regional concerns about Japan’s military past, and supports the regional stability that Japan seeks.
