Rising Nuclear Tensions: U.S. Legislation and Global Proliferation Concerns

On March 25, 2026, Senators Edward J. Markey (D-Mass.) and Jeff Merkley (D-Ore.) reintroduced the No Nuclear Weapons for Saudi Arabia Act, aimed at restricting Saudi Arabia's access to nuclear weapons technologies. This legislation mandates that any nuclear cooperation agreement with Saudi Arabia must receive Congressional approval. The bill, which Congressman Brad Sherman (CA-32) leads in the House, was initially introduced by Markey in 2019 alongside former Senator Marco Rubio. Markey criticized the Trump administration for allegedly allowing Saudi Arabia to pursue nuclear capabilities while simultaneously launching military actions against Iran to prevent its nuclear development. He stated, “Let us be clear: allowing Saudi Arabia to develop nuclear weapons would be irresponsible and dangerous.” Merkley echoed these concerns, emphasizing that the proposed deal could enable Saudi Arabia to enrich uranium and reprocess nuclear reactor fuels, thereby increasing the risk of nuclear proliferation in the Middle East.

The global nuclear arsenal remains a pressing concern, with a recent report indicating that the number of nuclear warheads ready for use has increased significantly. As of early 2026, the world's nine nuclear-armed states possess approximately 12,187 warheads, with 9,745 of these being readily deployable. This trend raises alarms about the potential for rapid escalation and accidental use amid intensifying global conflicts. Hans Kristensen, director of the Nuclear Information Project, noted that the annual rise in deployed warheads is a "concerning development," particularly given the erosion of disarmament efforts and the recent lapse of the New START treaty between the U.S. and Russia.

Critics of current nuclear policies argue that the increasing number of nuclear weapons undermines global security. Raymond Johansen, chief of the Norwegian People's Aid, warned that the world is witnessing a reversal of constraints on nuclear dangers. Despite 99 countries supporting the Treaty on the Prohibition of Nuclear Weapons (TPNW), nuclear-armed states, including the U.S., continue to modernize their arsenals. Melissa Parke, head of the International Campaign to Abolish Nuclear Weapons, urged nations to abandon reliance on nuclear weapons for security, stating, “There is no shelter to be had under a nuclear umbrella.”

In response to the rising nuclear threats, French President Emmanuel Macron announced a new nuclear strategy on March 2, 2026, which includes increasing France's nuclear arsenal and enhancing cooperation with European allies. Macron emphasized the need for a robust deterrent capability, stating, “My responsibility is to ensure that our deterrence maintains — and will maintain in the future — its assured destructive power.” This shift reflects broader concerns within Europe regarding reliance on U.S. defense commitments amid geopolitical tensions.

While the number of nuclear warheads has decreased from Cold War peaks, the increase in those ready for immediate use presents a complex picture of global nuclear dynamics. The disparity between the number of countries supporting disarmament and those expanding their arsenals highlights a critical gap in international nuclear governance.
