The New START treaty expired at midnight on February 5, 2026, ending more than five decades of binding restrictions on the strategic nuclear arsenals of the United States and Russia.[1]
Roots in Cold War Diplomacy
New START emerged from a long tradition of arms control. Presidents Barack Obama and Dmitry Medvedev signed the agreement in Prague in 2010. It entered force the following year after Senate ratification.
The treaty imposed strict numerical ceilings. Each side faced caps on deployed strategic nuclear warheads, delivery systems, and launchers. Compliance relied on robust verification.[2]
- 1,550 deployed warheads on intercontinental ballistic missiles, submarine-launched ballistic missiles, and heavy bombers.
- 700 deployed ICBMs, SLBMs, and heavy bombers equipped for nuclear arms.
- 800 total deployed and non-deployed ICBM launchers, SLBM launchers, and heavy bombers.
Before Russia’s suspension, teams conducted 328 on-site inspections. The parties exchanged over 25,000 notifications on movements and status changes. Biannual data declarations fostered transparency.[1]
Russia’s Suspension Seals the End
Tensions over Ukraine prompted Russia to suspend participation in February 2023. Moscow halted inspections and data exchanges while claiming adherence to numerical limits. The United States condemned the move as irresponsible.
Leaders extended the pact in 2021 for five years, pushing the deadline to February 4, 2026. No successor negotiations materialized. President Vladimir Putin proposed voluntary adherence for one more year in September 2025. The offer drew no formal U.S. reply.[3]
President Donald Trump dismissed concerns in January. He called for a broader deal including China. Russia’s Foreign Ministry labeled the U.S. stance erroneous yet affirmed a responsible approach moving forward.
Heightened Risks in a Multipolar World
Experts warn of renewed uncertainty. Without on-site checks, each side loses direct insight into the other’s capabilities. Satellite imagery and intelligence provide estimates, but gaps persist.[4]
China’s arsenal adds complexity. Beijing holds about 600 warheads now. Projections suggest over 1,000 by 2030 amid rapid modernization. The Pentagon highlighted this expansion in its 2025 report. Trump officials prioritize trilateral talks, though China has rebuffed invitations.
| Nation | Deployed Warheads (Approx.) | Trend |
|---|---|---|
| United States | ~1,550 | Modernizing |
| Russia | ~1,447 (2020 data) | Modernizing |
| China | ~600 | Expanding rapidly |
Both superpowers modernize forces. Russia develops hypersonic systems and novel delivery vehicles. The U.S. advances missile defenses. Such steps could spark escalation spirals.
Global Leaders Sound the Alarm
United Nations Secretary-General António Guterres described the lapse as a grave moment for peace. He urged swift negotiations for a successor regime. Pope Leo echoed calls to avert a new arms race.[1]
Dmitry Medvedev noted the loss of verification mechanisms. Former negotiator Nikolai Sokov lamented the personal and strategic setback. Analysts like Daryl Kimball foresee a costly three-way competition unless diplomacy intervenes.[3]
Key Takeaways
- No binding limits exist on U.S. and Russian strategic nuclear forces for the first time since the 1970s.
- Verification tools like inspections and notifications have ceased, raising miscalculation risks.
- China’s growth demands a broader arms control framework, though talks remain stalled.
