Final Nuclear Arms Control Agreement Between United States and Russia Ends

The last remaining nuclear arms control agreement between the United States and Russia has expired, removing formal limits on strategic nuclear arsenals. The lapse marks a major shift in global arms control frameworks.

Diplomatic efforts to negotiate a replacement agreement have stalled amid worsening geopolitical relations. Experts warn that the absence of binding limits increases risks related to escalation, miscalculation, and reduced transparency.

International leaders and arms control advocates have called for renewed dialogue to prevent destabilization of the global security environment.
