Article 1: New beginnings

Why in news: The New START Treaty expired on February 5, 2026, ending U.S.–Russia nuclear limits and raising concerns over renewed arms races and weakened global arms control frameworks.

 

Key Details

  • New START expired on February 5, 2026, ending U.S.–Russia nuclear limits
  • Cold War arms race led to over 10,000 warheads each by the 1980s
  • SALT (1970s) capped arsenals but did not reduce them
  • START I (1991) first mandated real reductions to 6,000 warheads
  • Later treaties cut limits to 1,700–2,200, then 1,550 under New START
  • Geopolitical shifts favour renewed arms-race doctrines
  • U.S. position links future arms control to China’s inclusion
  • Global regimes like NPT and CTBT may face erosion

 

Expiration of New START (February 5, 2026)

  • End of a landmark treaty
    • The New Strategic Arms Reduction Treaty (New START) officially expired on February 5, 2026
    • It symbolised a fading era of Cold War–style arms control cooperation

 

Cold War background to arms control

  • Era of nuclear one-upmanship
    • The United States and the Union of Soviet Socialist Republics (USSR) competed through
      • Testing massive nuclear weapons
      • Conducting space races and military demonstrations
  • Uncontrolled accumulation
    • By the 1980s, both sides possessed over 10,000 strategic nuclear warheads
    • The U.S. enjoyed a numerical and technological advantage

 

Early arms control efforts

  • Strategic Arms Limitation Talks (SALT), 1970s
    • Focused on capping nuclear arsenals
    • Did not require actual reductions
    • Failed to reverse the arms race trajectory

 

START I: a turning point

  • Negotiations and signing
    • Talks began in 1982
    • Treaty signed in July 1991, shortly before the USSR collapsed
  • Key achievements
    • First agreement to reduce, not just limit, nuclear weapons
    • Each side restricted to
      • 6,000 strategic warheads
      • Proportional reductions in delivery systems
    • Resulted in roughly 30% fewer warheads than earlier limits allowed

 

Progress beyond START I

  • Subsequent reductions
    • Later agreements lowered deployable warheads to 1,700–2,200 per side
  • New START (2010)
    • Capped deployed strategic warheads at 1,550 each
    • Marked a steady decline from Cold War peaks

 

Why New START was not replaced

  • Shifting global geopolitics
    • Return of imperialist tendencies
      • Mercantilist tariff systems
      • Renewed competition for territory and influence
  • Revival of arms-race thinking
    • Arms control seen as a constraint rather than a stabiliser

 

U.S. position and China factor

  • Conditional arms control
    • U.S. President Donald Trump stated future treaties must include China
    • Argument: the U.S. will not accept limits if
      • Other major powers are free to expand nuclear stockpiles

 

Implications for global nuclear regimes

  • Threat to broader agreements
    • Potential weakening of
      • Non-Proliferation Treaty (NPT)
      • Comprehensive Nuclear-Test-Ban Treaty (CTBT)
  • Structural criticism
    • NPT viewed as discriminatory, dividing nuclear “haves” and “have-nots”

 

A possible opportunity

  • Restarting dialogue
    • End of START could reopen discussions
    • Scope for more equal and inclusive arms control frameworks
    • Chance to rethink nuclear restraint on fairer global terms

 

Conclusion

The expiry of New START marks the collapse of the last major U.S.–Russia arms control framework, increasing risks of a renewed nuclear arms race. It may weaken global non-proliferation regimes like the NPT and CTBT, yet also offers an opportunity to revive inclusive, equitable arms control negotiations suited to today’s multipolar world.
