The world is on the brink of a potential nuclear arms race as the US and Russia's last remaining treaty, the New START agreement, expires on February 4, 2026. This marks a significant turning point in global nuclear security, leaving the two largest nuclear powers without any limits on their arsenals for the first time in decades. The implications are dire, with experts warning of a rapid escalation to a nuclear conflict if tensions are not managed carefully.
Thomas Countryman, a former US official, warns of the worst-case scenario: a conflict that quickly escalates to nuclear warfare. This fear is not unfounded, as the absence of treaty constraints could lead to a dangerous arms race. The New START treaty, which came into effect in 2011, set limits on both countries' nuclear capabilities, including the number of deployed warheads, missiles, and launchers. However, critics argue that these limitations were outdated and that the US was unnecessarily constrained, especially with China's growing nuclear arsenal in mind.
China's nuclear expansion is a significant concern. According to Pentagon reports, China could possess around 1,500 nuclear warheads by 2035 if its current expansion pace continues. This lack of coverage in the New START treaty has been a point of contention, as critics, including President Trump, argue that it should include China. However, Beijing has consistently rejected trilateral negotiations, making it challenging to address this issue.
The Trump administration's response to the treaty's expiration is uncertain. While Trump initially expressed interest in extending the treaty, he has since shown little concern, stating that a new agreement will be negotiated. Secretary of State Marco Rubio suggests that the US may not agree to maintain the treaty's limits, advocating for a trilateral deal involving the US, Russia, and China. However, Russia's Foreign Ministry has expressed disappointment, indicating that their ideas have been ignored.
Experts debate the benefits of extending the treaty's limits. Some argue that it's in the US's national security interest to maintain the treaty, ensuring predictability and transparency in nuclear programs. Paul Dean, a former assistant secretary, emphasizes the importance of avoiding an arms race and potential miscommunication. However, others, like Matthew Kroenig, suggest that the US should focus on deterring nuclear war with Russia and China, considering China's growing nuclear capabilities.
The Biden administration has taken steps to prepare for potential treaty revisions, but the exact course of action remains unclear. The US may increase its nuclear warheads, reversing previous treaty compliance measures. Some experts believe this is necessary to reassure allies, while others warn of a rapid Russian response if the US expands beyond treaty limits. The situation is complex, with potential consequences for global nuclear stability and the future of arms control.
