Russian President Vladimir Putin offered a one-year extension of the New START nuclear arms treaty with the U.S., set to expire on February 5, 2026, stressing global non-proliferation, while linking it to Washington’s reciprocal adherence and broader security tensions.
Description:
- Full Name: New Strategic Arms Reduction Treaty (New START).
- Parties: USA & Russia.
- Signed: 8 April 2010, Prague.
- Came into force: 5 February 2011.
- Extension: Extended for 5 years in Feb 2021 (till Feb 2026).
- Replaced: START I (1991, expired in 2009) and SORT (2002, terminated once New START entered force).
Objectives & Provisions:
- Limit deployed strategic nuclear warheads to 1,550 each.
- Limit deployed ICBMs, SLBMs, and heavy bombers to 700 each.
- Limit total launchers (deployed + non-deployed) to 800.
- Provides verification regime → data exchanges, notifications, inspections.
- Seeks to maintain stability while reducing Cold War–era arsenals.
Timeline:
- 2010 → Signed (Obama & Medvedev).
- 2011 → Entered into force.
- 2018 → Both countries announced they met treaty limits (by Feb 5, 2018).
