Last month, I looked at the legal implications of a conflict between China and Japan, concluding that the likelihood remains low, and that America would not be legally bound to defend Japan:
First of all, it is critical to note that the United States is not legally obligated under its with Japan treaty to intercede on Japan’s behalf. The treaty states that the United States is required to report any such event to the UN Security Council, instead:
Each Party recognizes that an armed attack against either Party in the territories under the administration of Japan would be dangerous to its own peace and safety and declares that it would act to meet the common danger in accordance with its constitutional provisions and processes. Any such armed attack and all measures taken as a result thereof shall be immediately reported to the Security Council of the United Nations in accordance with the provisions of Article 51 of the Charter. Such measures shall be terminated when the Security Council has taken the measures necessary to restore and maintain international peace and security.
