As to the initiative aspect, was the fact that, under international cold war background, the U.S. was eager to make Japan an anti-communism soldier in capitalism camp, to achieve its global strategy. For this reason, it should took some kind attitude to win over Japan. As to the passive aspect, which forced The U.S. government to make the some extent of concession, was that the Japanese domestic nationalism seriously threatened Japan’s conservative political power as well as the Japan-U.S. relationship, and one of its roots was the inappropriate "Japan-U.S. Security Treaty".
