- Abstract:
- A three-way nuclear arms race between the United States, China, and Russia looms — an escalation that would erode global nonproliferation and usher in an era of unchecked nuclear proliferation. This brief offers a path to preventing this destabilizing outcome through pragmatic nuclear cooperation — an approach that has strong historical precedent and accords with the strategic interests of all three nuclear superpowers. Superpower cooperation historically underpinned the global nuclear nonproliferation regime, but increasing great power competition erodes this entire system of international security. China and Russia have each modernized and expanded their nuclear programs and adopted more aggressive nuclear postures. The United States, in turn, has approved a nearly $2 trillion nuclear modernization program. This burgeoning arms race heightens risks of inadvertent escalation, as each of the superpowers become increasingly reliant on nuclear brinkmanship to hold off the growing capabilities of their adversaries. The deteriorating nuclear security environment places pressure on other states to similarly seek their own nuclear arsenals while weakening the nonproliferation tool kit that previously prevented these states from breaking out. As more armed states join the fray, they in turn multiply the number of potential nuclear flashpoints around the world. Reinvesting in superpower cooperation on nuclear security is not an idealistic bid for goodwill. Rather, halting unchecked competition is a pragmatic strategy that serves the interests of the United States, Russia, and China. It preserves a global nuclear system that has safeguarded the superpowers’ dominance for decades. Weakening it, on the other hand, undermines the international marketplace that has preserved U.S. dominance in private industry and innovation. Russia and China, in turn, risk a multifront nuclear competition, as proximate U.S. allies choose uncontrolled independent arsenals over existing security umbrellas. The superpowers can still step back from the abyss by reviving nuclear cooperation. Toward that objective, this brief recommends that the Trump administration: Accept Russia’s offer to extend New START for a year, paired with verification pathways and transparency measures. Reinvigorate existing direct lines of communication (i.e., hotline systems) with both Russia and China. Initiate trilateral nuclear discussions with Russia and China toward the goal of capping arsenals at parity on specific warheads and delivery systems.
