The creation of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in 1968 marked the first major shift towards nuclear disarmament that occurred on a global scale. The NPT is a landmark international treaty aimed at preventing the spread of nuclear weapons and weapons technology and achieving 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, that nuclear energy use remains peaceful, and that nuclear materials stay secure. The creation and enforcement of the NPT by the United Nations prompted talks between the United States and Russia to create mutual arms control agreements and reduce nuclear stockpiles. Beginning in November of 1969 with the presentation of SALT I, which limited each countries’ strategic missile defenses, the two nations went on to engage in more than half a dozen other nuclear-focused disarmament treaties with one another.
The New START Treaty between Russia and the United States was renewed in 2021. The renewal was significant because it assured both countries’ continued commitment to regulating and limiting nuclear weapons and weapons technology, and because of the upcoming review of the NPT that occurred later this year. However, 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 in 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, and 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 gives the U.S invaluable national security information by providing insights on the Russian nuclear arsenal, and maintains the 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.
