1968 marked the first major shift towards nuclear disarmament on a global scale with the creation of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). The NPT is a landmark international treaty whose primary objective is to prevent the spread of nuclear weapons and weapons technology and to achieve international disarmament. The treaty itself has culminated in a “grand bargain” between nuclear powers and non-nuclear powers to ensure that no new nuclear weapons can be acquired, nuclear energy use remains peaceful, and nuclear materials stay secure. The creation and enforcement of the NPT by the United Nations prompted talks between the United States and Russia, formerly known as the Soviet Union, in regards to the creation of mutual arms control agreements and the reduction of nuclear stockpiles. The two nations would go on to engage in more than half-a-dozen nuclear-focused disarmament treaties, beginning in November of 1969 with SALT I which limited each countries’ strategic missile defenses.
The New START Treaty between Russia and the United States was renewed in 2021. This is significant because it assures continued commitment to the regulation and limitation of nuclear weapons and weapons technology, but it is also important in light of the upcoming review of the NPT that is anticipated to occur in August of 2021. Despite the success of the NPT over the past 50 years, there is a growing concern that existing agreements, including the Intermediate-Range Nuclear Forces (INF) Treaty, are unraveling. Experts hope that because of the transparency in U.S.-Russian strategic relations that New START has provided, the rest of the world will follow suit and the NPT review conference will be a space to promote stability and strengthen commitments by signatories of the NPT.
The New START treaty, which was signed on April 8, 2010 by the U.S. and Russia, legally binds each state to limit their strategic nuclear warheads to 1,550 on 700 strategic delivery systems as well as limits each side to 800 deployed and non-deployed launchers. This limit is 30% lower than the previously allowed 2,200 nuclear warhead amount agreed upon in the 2002 SORT Treaty and 50% lower than the 1,600 vehicle delivery limit established under the 1991 START 1 agreement. In addition to major limits on each country’s physical nuclear stockpiles, the treaty also commits each state to mandatory, on-site inspections of nuclear storage and production facilities, data exchanges, and notifications related to strategic offensive arms and facilities covered by this treaty. New START entered into force on February 5, 2011, after both parties had signed and gained Senate and parliamentary approval in their respective governments, and both parties recently agreed to extend the treaty by five years in January of 2021.
New START provides invaluable national security information to the U.S. by providing insights on the Russian nuclear arsenal, as well as maintains an international standard for nuclear non-proliferation by the world’s two largest nuclear powers. In a larger sense, the treaty creates a stable base on which to uphold the major international arms control treaties such as the NPT, Treaty on the Prohibition of Nuclear Weapons (TPNW), and the Comprehensive Test Ban Treaty (CTBT). The renewal of New START by the U.S. and Russia is particularly important for the continued support and upholding of the NPT because although its global support is strong, statements by members of civil society confirm that its long-term viability needs to be continually addressed. The U.S. and Russia have had contentious relations dating back to Soviet-era politics, and the constant imbalance between competition and cooperation perpetuates their struggle to coexist. START is significant for what it aims to achieve in terms of international arms control measures, but also because it is one issue that the U.S. and Russia have been able to work together and agree upon. Although bilateral relations have sharply deteriorated when it comes to other international security issues such as offensive cybersecurity, counter-space, and hypersonic weapons, nuclear non-proliferation remains an issue that the U.S. and Russia actively cooperate with.
