New START treaty expires removing US–Russia nuclear limits
Expiry ends binding limits on strategic nuclear arsenals
Change
The New START treaty expired, ending legally binding limits on US and Russia strategic nuclear weapons.
Why it matters
The expiry removes caps on deployed nuclear warheads and verification mechanisms between the US and Russia. It eliminates inspection, reporting, and compliance frameworks governing nuclear arsenals.
Implications
- — Defense and security planners must reassess nuclear posture — absence of limits increases strategic risk
- — Intelligence agencies must rely on independent monitoring — loss of verification raises uncertainty
