The Next Era of Nuclear Arms Control

Author: U.S. Secretary of State Marco Rubio

During the Cold War, few negotiations proved as complex as those between the United States and the Soviet Union to limit and reduce their vast nuclear arsenals. They required trust between adversaries who had little reason to believe each other’s words, and they relied on intricate, constant systems to verify compliance. American statesmen persevered and reached a series of agreements first with the Soviet Union and then the Russian Federation that left the United States safer.

Everything has its season though and yesterday, New START expired. Arms control advocates and many voices in the media have tried to cast the expiration as a sign that the United States is initiating a new nuclear arms race. These concerns ignore that Russia ceased implementing the New START treaty in 2023, after flouting its terms for years. A treaty requires at least two parties, and the choice before the United States was to bind itself unilaterally or to recognize that a new era requires a new approach. Not the same old START, but something new. A treaty that reflects that the United States could soon face not one, but two, nuclear peers in Russia and China.

China’s rapid and opaque expansion of its nuclear arsenal since New START entered into force has rendered past models of arms control, based upon bilateral agreements between the United States and Russia, obsolete. Since 2020, China has increased its nuclear weapons stockpile from the low 200s to more than 600 and is on pace to have more than 1,000 warheads by 2030. An arms control arrangement that does not account for China’s build-up, which Russia is supporting, will undoubtedly leave the United States and our allies less safe.

President Trump has been clear, consistent, and unequivocal that future arms control must address not one, but both nuclear peer arsenals.

Our call for multilateral nuclear arms control and strategic stability talks, presented today in Geneva, reflects the principles President Trump has laid out.

First, arms control can no longer be a bilateral issue between the United States and Russia. As the President has made clear, other countries have a responsibility to help ensure strategic stability, none more so than China. Second, we will not accept terms that harm the United States or ignore noncompliance in the pursuit of a future agreement. We have made our standards clear, and we will not compromise them to achieve arms control for arms control’s sake. Third, we will always negotiate from a position of strength. Russia and China should not expect the United States to stand still while they shirk their obligations and expand their nuclear forces. We will maintain a robust, credible, and modernized nuclear deterrent. But we will do so while pursuing all avenues to fulfill the President’s genuine desire for a world with fewer of these awful weapons.

We understand that this process can take time. Past agreements, including New START, took years to negotiate and were built upon decades of precedent. They were also between two powers, not three or more. However, just because something is hard does not mean we should not pursue it or settle for less. No one understands that difficult deals are often the only ones worth having more than President Trump, who has repeatedly underscored the awesome power of nuclear weapons and his desire to reduce global nuclear threats. Today in Geneva, we are taking the first steps into a future where the global nuclear threat is reduced in reality, not merely on paper. We hope others will join us.

Marco Rubio was sworn in as the 72nd Secretary of State on January 21, 2025. The Secretary is creating a Department of State that puts America First.
