On the surface, the end of New START looks like a bilateral problem—another casualty of deteriorating U.S.–Russia relations. But beneath the treaty’s expiration date lies something far larger: the unravelling of the last surviving architecture that has kept nuclear competition bounded for more than half a century.
When President Barack Obama stood in Prague in 2010, he warned that New START was “just one step on a longer journey”
The journey, he knew, would be fragile. What neither side fully anticipated was how quickly the terrain itself would change—and how costly the loss of structure would be not only for Washington and Moscow, but for global security as a whole.
Why New START Mattered to the World, Not Just Two Capitals
New START was negotiated in a moment when the United States explicitly framed arms control as a global public good. The 2010 Nuclear Posture Review emphasized that the United States and Russia, holding the vast majority of the world’s nuclear weapons, bore a unique responsibility for stability. As Senate testimony noted, arms control helped ensure that “having fewer nuclear weapons reduces the danger that these weapons and nuclear materials might fall into the wrong hands”
The treaty’s verification regime—data exchanges, inspections, telemetry sharing—did more than reassure Washington. It reassured allies under the U.S. nuclear umbrella, reduced incentives for proliferation, and reinforced the credibility of the Nuclear Non-Proliferation Treaty (NPT). As Obama emphasized at the signing, New START was about demonstrating “responsible global leadership” and fulfilling commitments under the NPT
In other words, New START functioned as a stabilizing signal to the entire international system.
Russia’s Suspension: Strategy, Not Suddenness
Russia’s 2023 suspension of participation in New START did not emerge from a vacuum. In Chapter 8 of my book: Global Hegemony: A Strategic Illusion I made it clear that Moscow’s dissatisfaction had been building, driven by what it perceived as a deteriorating strategic balance and an erosion of mutual restraint.
President Vladimir Putin’s later explanation offers a candid window into this logic. In announcing Russia’s willingness to extend the treaty’s central quantitative limits for one year, he simultaneously warned that U.S. actions—particularly missile defense—were destabilizing. He singled out American plans to expand strategic missile defense, including “preparations for the deployment of interceptors in outer space,” arguing that such measures could “nullify our efforts to maintain the status quo” in strategic offensive arms
Russian Foreign Minister Sergei Lavrov reinforced this view, stressing that Russia’s proposal was a “unilateral gesture of goodwill,” but one contingent on U.S. restraint and respect for strategic balance
From Moscow’s perspective, then, suspension was leverage—an attempt to signal that arms control could not be decoupled from broader strategic concerns.
The FY2024 Strategic Posture Commission acknowledges this dynamic bluntly, condemning Russia’s “unwarranted and illegal” suspension while warning that the United States can no longer assume arms control will remain intact amid worsening geopolitical rivalry
A Numbers-Only Extension: Stability or Strategic Self-Deception?
Against this backdrop, Putin’s offer to extend New START’s central quantitative limits only may appear pragmatic. But pragmatism without structure is dangerous.
The 2010 Nuclear Posture Review repeatedly emphasized that reductions were acceptable because they were verifiable. The treaty provided “detailed monitoring and transparency provisions” that supplemented national technical means, including up to “18 on-site inspections per year” and extensive data exchanges
These mechanisms transformed numerical limits into strategic confidence.
By contrast, a one-year extension without restored inspections or data exchanges asks the United States to accept restraint without reassurance. It reverses the original bargain of New START and risks creating what looks like stability but functions as uncertainty.
The FY2024 Strategic Posture Commission cautions explicitly against this mindset. It warns that U.S. strategy “cannot be based on the assumption that arms control agreements are imminent or will always be in force,” especially given “Russia’s history of noncompliance and illegal treaty suspensions”
Risk reduction, the Commission notes, remains essential—but only when it genuinely reduces misperception rather than masking it.
The Global Security Fallout of Losing the Last Guardrail
The collapse of New START would not simply unleash a bilateral arms race. It would reverberate globally.
First, it would weaken the NPT regime. Putin himself acknowledged that abandoning New START would have “adverse implications” for the NPT.
When the two largest nuclear powers abandon limits, the credibility of nonproliferation norms erodes.
Second, it would unsettle allies and partners. The FY2024 Strategic Posture Commission underscores that U.S. alliances are a strategic advantage, and that extended deterrence reassures more than thirty treaty allies.
A hollow arms control regime undermines confidence in U.S. situational awareness and crisis management—key pillars of alliance assurance.
Third, it increases miscalculation risk in a multipolar nuclear world. The Commission warns that unlike the Cold War, today’s environment features the potential for simultaneous crises involving multiple nuclear-armed states, with escalation risks far harder to manage
In short, the loss of New START’s structure amplifies insecurity far beyond Washington and Moscow.
The China Question and the Limits of a Tripartite Future
No discussion of global nuclear stability today can ignore China. The FY2024 Strategic Posture Commission is unequivocal: China’s “unprecedented growth” has shattered the assumption that it could be treated as a “lesser-included” nuclear threat.
Does this mean a tripartite arms control agreement is the answer? Strategically, it may be necessary in the long run—but politically and structurally, it remains elusive.
China has repeatedly rejected participation in trilateral negotiations, even while praising Russia’s extension proposal. Moreover, the Commission recommends that any future arms control limits be developed only after the United States defines a strategy capable of deterring two nuclear peers simultaneously.
A future framework that includes China may be worth exploring—but only if it is verifiable, enforceable, and aligned with real force requirements. Without those conditions, multilateralism risks becoming symbolism rather than security.
Conclusion: Arms Control as Structure, Not Sentiment
New START was never an act of sentiment. It was an act of structure.
It worked because numbers were paired with knowledge, restraint with reciprocity, and reductions with verification. In 2010, that structure matched the strategic environment. In 2026, the environment is harsher—but that makes structure more necessary, not less.
Extending New START’s central limits without restoring its verification regime may slow visible competition, but it risks accelerating invisible danger. In a world the FY2024 Strategic Posture Commission describes as more dangerous and less predictable than at any point since the Cold War, illusion is not stability—it is exposure.
If New START is to endure—whether bilaterally now or multilaterally in the future—it must endure as architecture, not aspiration. Otherwise, the last remaining guardrail of the nuclear age will not fail loudly. It will fail quietly leaving the world less secure, less informed, and far closer to the edge.
