Is the Era of Nuclear Arms Control Coming to an End?
The United Nations has warned of a dangerous turning point in global security as the New START treaty—the last major nuclear arms control agreement between the United States and Russia—has officially expired.
UN Secretary-General António Guterres described the moment as “extremely dangerous and badly timed,” cautioning that the treaty’s collapse could push the world toward a new and uncontrolled nuclear arms race amid rising global tensions.
What New START Did
Signed in 2010 and extended once in 2021, the New START treaty limited both Washington and Moscow to:
- 1,550 deployed strategic nuclear warheads
- 700 deployed missiles and heavy bombers
Equally critical was its mutual inspection regime, which allowed on-site verification and transparency—helping prevent miscalculation and build trust between the two nuclear superpowers.
With the treaty now expired, all legal limits and verification mechanisms have disappeared.
Why the Expiry Is So Dangerous
Guterres warned that without binding limits or inspections, nuclear stockpiles could grow rapidly.
“Without ceilings or verification,” he said, “the risk of a destabilising and dangerous cycle of escalation is real.”
Analysts note that this is the first time in nearly five decades that the United States and Russia are left without anybilateral nuclear arms control agreement. Both countries now have the technical capacity to significantly expand their warhead numbers and delivery systems.
Positions of Washington and Moscow
Russia suspended participation in New START inspections in 2023 but had said it would continue to respect the numerical limits. With the treaty’s expiration, that commitment is no longer binding.
President Vladimir Putin has suggested Russia may voluntarily observe some limits, but has rejected a full return to inspections under current sanctions and diplomatic tensions.
The United States, meanwhile, has insisted that meaningful arms control must remind verification and transparency—conditions Moscow currently views as unrealistic.
Global Impact and What Comes Next
Experts warn the consequences may extend beyond Washington and Moscow. Other nuclear-armed states, including China, could be drawn into a renewed arms race, further weakening the global non-proliferation framework.
Guterres has called for urgent diplomacy under the UN’s leadership, urging both sides to begin negotiations on a new framework before strategic stability erodes further.
The world is now watching closely to see whether the end of New START becomes the trigger for renewed dialogue—or the opening chapter of a more dangerous nuclear era.
