The 1952 Mutual Security Assistance Pact provided the initial basis for the nation's security relations with the United States. The pact was replaced in 1960 by the Treaty of Mutual Cooperation and Security, which declares that both nations will maintain and develop their capacities to resist armed attack in common and that each recognizes that an armed attack on either one in territories administered by Japan will be considered dangerous to the safety of the other. The Agreed Minutes to the treaty specified that the Japanese government must be consulted prior to major changes in United States force deployment in Japan or to the use of Japanese bases for combat operations other than in defense of Japan itself. However, Japan was relieved by its constitutional prohibition of participating in external military operations from any obligation to defend the United States if it were attacked outside of Japanese territories. In 1990 the Japanese government expressed its intention to continue to rely on the treaty's arrangements to guarantee national security.
