The Impending Expiration of New START: A Turning Point in Global Nuclear Stability

Juba, South Sudan – January 8, 2026
The world stands on the brink of a new era in nuclear arms control—or the lack thereof—as the New Strategic Arms Reduction Treaty (New START), the last remaining bilateral nuclear arms limitation agreement between the United States and Russia, approaches its expiration on February 5, 2026. Signed in 2010 and extended once in 2021, this treaty has been a cornerstone of strategic stability, capping the deployed nuclear arsenals of the two nations that collectively possess over 90% of the world’s nuclear weapons. With no successor agreement in sight and formal talks stalled amid heightened geopolitical tensions, experts warn of increased risks of uncontrolled arms escalation, miscalculation, and potential catastrophe.
The Origins and Achievements of New START
New START, formally known as the Treaty on Measures for the Further Reduction and Limitation of Strategic Offensive Arms, was signed by U.S. President Barack Obama and Russian President Dmitry Medvedev in Prague on April 8, 2010, entering into force in February 2011. It replaced earlier treaties like START I (1991) and the Moscow Treaty (2002), continuing a post-Cold War tradition of verifiable reductions in strategic nuclear forces.
The treaty’s central limits are straightforward yet profound:
- 1,550 deployed strategic nuclear warheads per side.
- 700 deployed intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and heavy bombers.
- 800 total deployed and non-deployed launchers.
These caps, combined with robust verification mechanisms—including up to 18 on-site inspections per year, data exchanges, and notifications—provided transparency and predictability. Both nations met the limits by 2018 and have largely adhered to them since, reducing deployed warheads from Cold War peaks of tens of thousands to levels not seen since the 1960s.
The treaty was extended for five years in 2021 under the Biden administration, pushing its expiration to 2026. However, it cannot be extended again without a new agreement, as its terms allow only one such prolongation.
The Current Crisis: Suspension and Stalled Talks
Tensions escalated in February 2023 when Russian President Vladimir Putin announced Russia’s “suspension” of participation in New START, citing U.S. support for Ukraine in the ongoing war and alleged violations by Western allies. Russia pledged to continue respecting the numerical limits but halted inspections, data exchanges, and notifications. The U.S. responded with countermeasures, declaring Russia’s suspension “legally invalid” while also abiding by the caps.
Verification has effectively collapsed, raising concerns about hidden buildups. Although both sides claim compliance, the absence of on-site inspections erodes confidence. U.S. assessments suggest Russia has not significantly exceeded limits, but uncertainty persists.
Formal negotiations for a successor treaty have not materialized. The war in Ukraine has poisoned bilateral relations, with Russia conditioning any talks on Western concessions regarding NATO and Ukraine. The U.S., under the current Trump administration, has expressed interest in broader arms control involving China but has not initiated direct successor discussions.
Putin’s Proposal and the U.S. Response
In September 2025, President Putin proposed a one-year informal extension: both sides would voluntarily adhere to New START’s central quantitative limits after February 5, 2026, without formal treaty obligations. This “political commitment” could buy time for negotiating a replacement, potentially including flexible limits to account for China’s growing arsenal.
President Donald Trump initially responded positively, calling it “a good idea,” but no formal U.S. acceptance has followed as of early January 2026. Analysts are divided: some see it as a low-cost way to maintain stability and signal restraint to China; others argue it rewards Russia’s treaty suspension, lacks verification, and constrains U.S. responses to dual threats from Russia and China.
The Trump administration’s broader policy emphasizes nuclear modernization and potential expansion. Influences from conservative blueprints like Project 2025 advocate uploading additional warheads, developing new delivery systems, and preparing for a multi-peer nuclear environment. Rejecting an extension could allow the U.S. to rapidly increase deployed forces, leveraging existing reserves.
Risks of Expiration: An Unconstrained Nuclear Landscape
For the first time since 1972, no legally binding limits will constrain U.S. and Russian strategic nuclear forces post-February 2026. Experts highlight several dangers:
- Arms Race Acceleration: Both nations could quickly “upload” warheads from reserves. Russia might increase by 60%, while the U.S. could double its ICBM force. Modernization programs—U.S. Sentinel ICBMs, Russian Sarmat missiles—would proceed unchecked.
- Reduced Transparency: Without inspections and data exchanges, miscalculations could rise. National technical means (satellites) can monitor launchers but struggle with warhead counts.
- Proliferation and Global Implications: Expiration undermines the Nuclear Non-Proliferation Treaty (NPT), signaling to non-nuclear states that disarmament commitments are hollow. The 2026 NPT Review Conference looms as a potential flashpoint.
- China Factor: Beijing’s arsenal is expanding rapidly (projected 1,000+ warheads by 2030), but outside any limits. A U.S.-Russia race could accelerate this tri-polar dynamic.
Some propose unilateral restraint or transparency measures post-expiration, but without mutual agreement, momentum favors buildup.
Pathways Forward: Hope Amid Uncertainty
Despite pessimism, options remain:
- Accept Putin’s one-year adherence proposal, possibly with added transparency.
- Negotiate a multilateral framework including China (though Beijing has resisted).
- Resume full New START implementation until expiration to rebuild trust.
Arms control advocates urge urgent diplomacy, noting that even Cold War rivals negotiated amid crises. As one expert remarked, “New START’s end doesn’t have to mean the end of restraint—but it will require political will both sides have yet to fully demonstrate.”
In an increasingly volatile world—from Ukraine to Taiwan tensions—the expiration of New START serves as a stark reminder of nuclear risks. As February 5 approaches, the decisions made in Washington and Moscow will shape global security for decades.
