Strategic Offensive Reductions Treaty (SORT)

The Strategic Offensive Reductions Treaty (SORT) required both the United States and the Russian Federation to reduce and limit their strategic nuclear warheads to a certain number, determine the composition and structure of their offensive arms, and agree that the Strategic Arms Reduction Treaty I (START I) remain in force. SORT did not have any verification or compliance provisions. Yet, both states agreed to meet at least twice a year at the Bilateral Implementation Commission (BIC) for progress updates. The treaty allowed for withdrawal upon 90 days of written notice.
