New START, signed in 2010 by Obama and Medvedev, capped U.S. and Russian strategic forces at 1,550 deployed warheads, 700 deployed launchers, and 800 total launchers.Source 2Source 4 It built on Cold War reductions, entering force in 2011 with verification like on-site inspections and data swaps.Source 1Source 2

Extended by five years in 2021, it expires February 5, 2026—marking the end of bilateral limits since SALT I in 1969.Source 1Source 3 Russia's 2023 suspension halted inspections, yet both affirm numerical compliance.Source 1Source 2

Putin paused Russia's participation in February 2023; the U.S. reciprocated, freezing transparency but not numbers.Source 1Source 2 In September 2025, Putin offered a one-year voluntary extension of limits if the U.S. reciprocates—no U.S. response yet.Source 4

Talks stall over Ukraine, missile defenses, and China's role. Trump eyes a 'better' deal including Beijing, but China balks with its smaller ~600-warhead arsenal versus U.S./Russia's 5,000+.Source 2Source 4 Re-ratification faces slim U.S. Senate odds.Source 1

No limits mean uncertainty drives planning—uploading warheads or expanding systems could ignite races.Source 2Source 7 Even without buildups, lost transparency heightens crisis risks.Source 1Source 2

Ahead of the 2026 NPT Review, expiry signals nuclear powers abandoning restraint, eroding the treaty's credibility.Source 2 U.S. 'Golden Dome' defenses may push Russia/China to diversify offenses.Source 2

Short-term: One-year voluntary limits buy time without full verification—imperfect but vital.Source 1Source 2Source 4 Long-term new treaty needs definitions, trust, and diplomacy—unrealistic soon.Source 2

Multilateral inclusion desirable but risky; focus on bilateral revival preserves stability while engaging others.Source 2 Both need arms control: as Putin noted, their weapons are too destructive for use.Source 4

In a tense world, New START's end revives unconstrained arsenals, threatening global security.Source 6Source 7 It underscores arms control's fragility—yet history shows pacts possible even in rivalry.Source 1

Renewed U.S.-Russia dialogue could avert escalation, reminding us limits saved the Cold War from hotter conflict.Source 2

  • Russia's 2023 suspension froze operations but kept quantitative caps.Source 1
  • U.S. missile defense plans like 'Golden Dome' fuel Russian expansion incentives.Source 2
