On February 5, 2026, the New Strategic Arms Reduction Treaty (New START)\u2014the last remaining bilateral nuclear arms control agreement between the United States and Russia\u2014officially expired at midnight GMT. For the first time in more than half a century, the world\u2019s two largest nuclear powers are no longer bound by verifiable limits on their strategic nuclear arsenals, ushering in an era of unprecedented uncertainty and heightened global nuclear risk.<\/p>\n\n\n\n

The treaty, originally signed in 2010 by Presidents Barack Obama and Dmitry Medvedev and extended for five years in 2021 under the Biden administration, capped each side at 1,550 deployed strategic nuclear warheads on up to 700 deployed intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and heavy bombers, with an overall limit of 800 deployed and non-deployed launchers. It also established robust verification mechanisms, including on-site inspections, data exchanges, and notifications\u2014elements that provided transparency and predictability in U.S.-Russian strategic relations since the Cold War era.<\/p>\n\n\n\n

With the treaty\u2019s expiration, these constraints vanish. Experts warn this could accelerate nuclear modernization programs, enable rapid \u201cuploading\u201d of additional warheads onto existing delivery systems, and fuel a dangerous three-way arms competition involving the United States, Russia, and China.<\/p>\n\n\n\n

The Road to Expiration: Failed Negotiations and Geopolitical Tensions<\/strong><\/p>\n\n\n\n

New START was designed with a 10-year term (expiring February 5, 2021) and one possible five-year extension, which both parties exercised amid hopes for a follow-on agreement. However, Russia\u2019s full-scale invasion of Ukraine in February 2022 severely damaged bilateral trust. In 2023, Moscow suspended its participation in treaty inspections and data exchanges, citing Western support for Ukraine and concerns over NATO\u2019s nuclear posture. The U.S. responded with countermeasures, declaring Russia\u2019s actions a material breach.<\/p>\n\n\n\n

Despite these strains, informal adherence to the numerical limits persisted for a time. In September 2025, Russian President Vladimir Putin proposed that both nations continue observing New START\u2019s central limits for one year post-expiration, with potential for extension if the U.S. reciprocated without undermining strategic balance. President Donald Trump initially described the idea as sounding \u201clike a good idea,\u201d but later remarked, \u201cIf it expires, it expires. We\u2019ll do a better agreement,\u201d emphasizing inclusion of China in future talks. No formal U.S. response materialized, and negotiations never advanced.<\/p>\n\n\n\n

The treaty could not be extended further without re-ratification\u2014a politically improbable path given U.S. Senate requirements and ongoing tensions. As a result, February 5, 2026, marked the end without a successor framework.<\/p>\n\n\n\n

Immediate Implications: Loss of Transparency and Verification<\/strong><\/p>\n\n\n\n

The treaty\u2019s demise eliminates critical stabilizing mechanisms:<\/p>\n\n\n\n

\u2022  No more biannual data exchanges on deployed forces.<\/p>\n\n\n\n

\u2022  No on-site inspections to verify compliance.<\/p>\n\n\n\n

\u2022  No notifications for missile tests or movements.<\/p>\n\n\n\n

This \u201ctransparency gap\u201d increases the risk of miscalculation. Without reliable information on the other\u2019s arsenal size, composition, or readiness, each side may assume the worst, prompting precautionary buildups or heightened alert postures.<\/p>\n\n\n\n

UN Secretary-General Ant\u00f3nio Guterres described the expiration as a \u201cgrave moment for international peace and security,\u201d noting that for the first time in over 50 years, the world lacks binding limits on U.S. and Russian strategic nuclear forces. He urged both nations to return swiftly to negotiations.<\/p>\n\n\n\n

The Emerging Three-Way Dynamic: Russia, U.S., and China<\/strong><\/p>\n\n\n\n

Russia continues modernizing its arsenal, including systems like the Sarmat ICBM and Avangard hypersonic glide vehicles\u2014previously constrained under New START. Experts estimate Russia could add hundreds of warheads relatively quickly by uploading spares onto existing missiles.<\/p>\n\n\n\n

The U.S. is pursuing its own modernization program (e.g., Columbia-class submarines, Sentinel ICBMs, B-21 bombers), framed as replacing aging systems rather than expansion. However, without limits, pressure could mount to increase deployed warheads to maintain deterrence parity.<\/p>\n\n\n\n

China\u2019s rapid buildup adds urgency. Beijing has roughly doubled its nuclear arsenal in recent years (from ~300 to ~600 warheads) and is projected to reach parity with U.S.\/Russian ICBM numbers by 2030. China has shown no interest in joining trilateral talks, viewing its smaller force as defensive.<\/p>\n\n\n\n

This creates a \u201ctwo-tier deterrence\u201d challenge for the U.S.: countering combined Russian and Chinese threats. Analysts fear an unconstrained multipolar arms race\u2014costly, destabilizing, and prone to escalation amid crises like Ukraine or Taiwan.<\/p>\n\n\n\n

Expert Warnings and Calls for Action<\/strong><\/p>\n\n\n\n

Arms control specialists highlight risks:<\/p>\n\n\n\n

\u2022  Rapid escalation in a crisis due to misperceptions.<\/p>\n\n\n\n

\u2022  Environmental and economic costs of renewed buildups.<\/p>\n\n\n\n

\u2022  Erosion of global non-proliferation norms.<\/p>\n\n\n\n

Many advocate short-term measures: mutual observance of New START limits informally, risk-reduction channels (e.g., military-to-military talks), and European leadership in pushing for renewed dialogue. Others note the legal obligation under the Nuclear Non-Proliferation Treaty to pursue disarmament negotiations remains intact.<\/p>\n\n\n\n

President Trump has signaled interest in a \u201cbetter\u201d deal encompassing China, but no concrete steps have emerged. Russia maintains it will act \u201cresponsibly\u201d as a nuclear power.<\/p>\n\n\n\n

As the world enters this uncharted post-New START era, the absence of guardrails amplifies nuclear dangers at a time of geopolitical volatility. Whether this becomes a prolonged suspension of arms control or a catalyst for new frameworks will depend on political will in Washington, Moscow, and beyond. For now, the clock has ticked closer to midnight.<\/p>\n\n\n\n
