The Strategic Offensive Reductions Treaty (SORT). Both the United States and Russia declared in 2002 their intention to greatly reduce their nuclear forces. On May 24, 2002, Russian President Vladimir V. Putin and U.S. President George W. Bush signed SORT, also known as the Moscow Treaty, under which the two sides agreed to reduce operationally deployed strategic warheads to between 1,700 and 2,200 each over the next 10 years. Although the treaty does not provide a timetable nor benchmarks to guide the rate of warhead reductions during this period, it does establish a Bilateral Implementation Commission, scheduled to meet at least twice a year, to discuss and review the treaty's implementation. The treaty will remain in force until December 31, 2012, at which time the parties have the option of extending or terminating the agreement. Each side may at any time cite its national sovereignty and withdraw from the Treaty after giving three months notice.

Verification measures, based on provisions found in the 1991 Strategic Arms Reduction Treaty (START I), will remain in force until 2009 to help ensure that warheads have been removed from launchers. However, like START I and other strategic arms control treaties, SORT does not specify what is to be done with the removed warheads. The SORT treaty also does not address tactical nuclear warheads that are part of the U.S. and Russian arsenals. A Joint Statement, also issued on May 24, 2002, establishes a Consultative Group for Strategic Security to discuss confidence-building measures and transparency issues, as well as other nuclear weapons issues not addressed by SORT.

In contrast to the START I treaty and the unimplemented START II treaty, SORT does not require the elimination of any strategic missiles, submarines, or bombers. Thus, it allows each country to keep its MIRVed ICBMs, as long as its overall total of operationally deployed strategic warheads is below 2,200 at the end of the treaty's 10-year period. Russia has indicated that it plans to retain its largest multiple-warhead ICBM, the 10-warhead SS-18 "Satan." The United States has announced plans to eliminate its largest multiple-warhead ICBM, the 10-warhead MX "Peacekeeper."

On March 6, 2003, the U.S. Senate approved the SORT treaty for ratification by a vote of 95-0.  Prior to the vote, the Senate Foreign Relations Committee had unanimously approved the accord.  The Committee also added two conditions to guide U.S. compliance, which were both accepted by President Bush.  These conditions require the president to provide Congress with annual reports on U.S. reductions of strategic arms, and on ways in which the Cooperative Threat Reduction program can help achieve Russian reductions. Furthermore, the FY2004 Defense Authorization Act included a section requiring the Director of Central Intelligence to submit to Congress an annual report concerning nuclear weapons dismantled by Russia during the prior fiscal year as well as the director’s projections for Russia’s compliance during the current year and the following year.

The Russian Duma, the lower house of the Russian parliament, ratified the SORT treaty on May 14, 2003, by a vote of 294-134; and the Federation Council, the upper house, approved the treaty on May 29.  Much like the ratification in the U.S. Senate, the Duma ratification of SORT was accompanied by two additional provisions.  The first requires the Russian president to submit annual reports on the U.S. strategic reductions.  The second requires annual reports on the status of missile defense programs of the United States and other countries.

Following the ratification by the U.S. Senate and the Russian Duma, Presidents Bush and Putin exchanged instruments of ratification at a 45-minute ceremony in St. Petersburg, Russia on June 1, 2003.  The treaty went into effect immediately.
