One aspect of the build up for war with China is the rearmament and increasingly aggressive military posture of Japan. Imperialists in Japan have long sought to shed the constraints placed on it as a defeated nation after the Second World War and now they have been given the green light to do this by the United States, which wants Japan to be part of the military encirclement of China and of Russia in the East. However, as the only country which has experienced the use of nuclear weapons at Hiroshima and Nagasaki, there is also a strong peace movement in Japan which rejects these moves.
