The impending expiration of the New START treaty in early February 2025 is poised to reshape the landscape of global nuclear security, potentially leaving the United States and Russia without mutual restrictions on their strategic arsenals for the first time in over half a century. This critical arms control agreement, which limits deployed strategic warheads and delivery systems, faces an uncertain future as last-minute negotiations appear stalled, raising the specter of a new and unconstrained nuclear arms race. The potential unraveling of the pact could see both superpowers free to expand their long-range missile and warhead deployments, triggering broader concerns about stability and fostering a more unpredictable international environment, further complicated by the rapid growth of China’s nuclear capabilities.
Russian President Vladimir Putin previously proposed a one-year extension of existing warhead limits, a measure intended to provide additional time for comprehensive negotiations on a successor agreement. However, formal responses from the US administration regarding this proposal have not materialized, leading to increased apprehension among global security analysts. The lack of a clear path forward risks dismantling decades of nuclear arms control architecture.
The implications extend beyond mere numerical limits on weapons, impacting several vital aspects of international security:
* Loss of transparency: Without the treaty, mutual inspections cease, reducing insight into each other’s nuclear activities.
* Breakdown of communication channels: Critical dialogue between nuclear powers becomes less frequent and formal.
* Increased risk of miscalculation: Reduced transparency and communication can heighten tensions and misunderstanding.
Global stability at risk as mutual controls lapse
The absence of the New START treaty would mark a profound shift, ending an era of mutual constraint on strategic arsenals that has been in place for over 50 years. This void means both Washington and Moscow could deploy and equip additional long-range missiles with nuclear warheads without bilateral oversight. Experts warn this scenario increases the risk of misjudgment and escalation, destabilizing the balance of power.
Darya Dolzikova, a nuclear expert at the RUSI think tank in London, emphasizes that nuclear treaties extend far beyond numerical limits. She explains these agreements create a transparent and stable framework essential for preventing an arms race from spiraling out of control, establishing vital communication channels for understanding each other’s concerns.
Complexities hinder future arms control efforts
Forging a new arms control agreement presents a formidable and time-consuming challenge, far more complex than when New START was negotiated in 2010. Russia has since developed a new generation of nuclear-capable systems—including the Burevestnik cruise missile, Oreshnik hypersonic missile, and Poseidon torpedo—all operating outside the expiring treaty’s parameters. Concurrently, former President Donald Trump announced plans for a space-based missile defense system known as the Golden Dome, a move Moscow views as a provocative attempt to unilaterally shift the strategic balance in Washington’s favor.
China’s growing nuclear power reshapes strategic calculus
A primary concern for the United States in future arms control discussions is China’s rapidly expanding nuclear arsenal. The Asian nation possesses an estimated 600 warheads, projected to exceed 1,000 by 2030, fundamentally altering the global nuclear landscape.
Former President Trump previously expressed a desire for “denuclearization” involving both Russia and China. Beijing has consistently stated it is unreasonable to expect them to join disarmament negotiations with two countries whose existing arsenals are vastly superior.
A bipartisan Congressional commission in 2023 warned the United States faces an “existential challenge” from not one, but two nuclear peers. The commission recommended the US prepare for potential simultaneous conflicts with both Russia and China, underscoring shifted strategic threat perception.
Divergent US views on Putin’s extension offer
Within US political circles, opinions remain sharply divided on whether the current administration should accept President Putin’s suggestion to maintain existing nuclear limits for another year. Proponents of arms control highlight significant domestic challenges.
These advocates point out that the ongoing US nuclear force modernization program, including new submarines, bombers, and intercontinental ballistic missiles, is plagued by serious delays and enormous cost overruns. The Congressional Budget Office estimates this will cost taxpayers nearly one trillion dollars between 2025 and 2034, making a pause or extension appealing.
The ongoing technological arms race is undeniable
Security analysts largely agree a new arms race is already underway, driven primarily by technological advancements. Prokhor Tebin, head of the Military-Economic Research Center in Moscow, notes the “constant development of high-precision non-nuclear weapons” alongside new technologies.
Tebin specifically mentioned “hypersonic technologies” as a key area of intense competition, highlighting that the arms race is certainly a technological one. This continuous innovation introduces new variables and challenges to traditional arms control frameworks.
In preparation for a potential post-treaty environment, experts suggest the US could restore strategic warheads removed under New START. This would involve re-equipping Minuteman III intercontinental ballistic missiles and Trident D5 submarine-launched ballistic missiles.
Another potential step involves returning approximately 30 B-52 strategic bombers, previously converted for conventional missions, back to their nuclear roles. Such actions would visibly demonstrate an increase in the US strategic arsenal, albeit a process likely spanning several years.
Diplomatic impasses and Russian resolve
On the other side of the debate, some US experts and former officials caution against trusting President Putin, citing Russia’s suspension of mutual inspections under New START in 2023. This suspension, prompted by US support for Ukraine, severed a crucial transparency mechanism.
Dmitry Medvedev, who as Russian President signed the original New START agreement in 2010, commented on the current landscape, describing US leadership as unpredictable. He affirmed, “Russia is prepared for any development. New threats to our security will be promptly and firmly countered,” indicating Moscow’s readiness for an unconstrained nuclear environment.
Beyond traditional deterrence: A multi-polar nuclear future
The complexities of global nuclear deterrence now extend far beyond the traditional bilateral framework between Washington and Moscow. Darya Dolzikova points out that while China has been reluctant to engage in arms control talks, Russians also factor in the nuclear forces of other nations like Britain and France, indicating a more multi-polar calculus in strategic planning.
