WASHINGTON: As the clock ticks down to February 5, the last remaining treaty limiting the number of deployed Russian and U.S. nuclear warheads is set to expire, introducing a new era of uncertainty in global nuclear policy. This expiration marks a pivotal moment, as both nations have had numerical restrictions on their nuclear arsenals for over 50 years, and the abandonment of these limits could unleash a new arms race.

In 2023, Russia suspended the New Strategic Arms Reduction Treaty (New START) in protest of U.S. military assistance to Ukraine, a move that prompted Washington to effectively put the agreement on hold as well. Despite Russian President Vladimir Putin's overtures to maintain the treaty's core terms—capping each country at 1,550 deployable warheads—there has been no significant U.S. response. The Biden administration continues to sidestep requests for dialogue on the matter, as concerns about an escalation of nuclear stockpiles loom large.

Pavel Podvig, a senior researcher at the United Nations Institute for Disarmament Research, commented on the likelihood of a proliferation surge. "If the limits set by New START are abandoned, we could expect a swift increase in both U.S. and Russian warhead counts, as both nations have the capability to enhance their existing nuclear platforms rapidly," he stated. The U.S. currently maintains 400 Minuteman III intercontinental ballistic missiles capable of carrying more warheads than they are currently allowed under treaty constraints.

The emergence of China as a significant nuclear player complicates the landscape further. Former U.S. defense officials recognize that the dynamics of nuclear deterrence are changing, as China is expected to field a stockpile of up to 1,500 nuclear warheads by 2035. This scenario leaves the U.S. and Russia grappling with how their nuclear strategies will evolve in response to a third power.

Daryl Kimball, the executive director of the Arms Control Association, stressed the importance of renewed nuclear control measures. He argued, "The reality is that more nuclear weapons will not make anyone safer." He highlighted the risk that renewed arms competition may destabilize existing nuclear deterrence frameworks, leading to potentially catastrophic consequences.

As the February expiration date approaches, international calls for diplomatic engagement and arms control measures grow louder, underscoring the urgent need for a reassessment of nuclear policies in an increasingly perilous geopolitical environment.
