U.S. Considers Expanding Nuclear Arsenal After New START Expiration
2/11/2026, 5:58:52 AM
Overview of the Core Event
The United States is contemplating an expansion of its nuclear arsenal and the potential resumption of underground nuclear testing following the expiration of the New START treaty, the last significant arms control agreement with Russia. This shift marks a significant departure from decades of U.S. policy aimed at limiting nuclear weapons.
Background on New START Treaty
The New START treaty, signed in 2010, capped the number of deployed strategic nuclear warheads for both the U.S. and Russia at approximately 1,550 each. It also limited the number of missiles and bombers to 800 and included provisions for short-notice inspections to verify compliance. However, these inspections ceased during the COVID-19 pandemic, and Russia announced in 2023 that it would end inspections entirely, despite pledging to comply with the treaty's limits.
Key Developments Following Expiration
With the New START treaty lapsing, U.S. officials, including Thomas DiNanno, the State Department’s undersecretary for arms control, have expressed concerns about the treaty's constraints. DiNanno criticized the treaty for placing "unilateral constraints" on the U.S. while allowing Russia and China to expand their nuclear capabilities. He indicated that the U.S. could now take steps to strengthen its nuclear deterrence, including reactivating missile tubes on Ohio-class submarines that had been disabled under treaty limits.
Official Statements & Responses
President Donald Trump rejected a Russian proposal for an informal extension of the New START treaty, advocating instead for a "new, improved and modernized" nuclear arms control agreement. DiNanno emphasized that the U.S. is now free to explore options for expanding its nuclear forces and potentially resuming nuclear testing, which would reverse nearly 40 years of stricter nuclear control.
Criticism & Opposition
Critics of the U.S. administration's approach argue that expanding the nuclear arsenal could exacerbate global tensions and lead to a renewed arms race. The executive secretary of the Comprehensive Nuclear-Test-Ban Treaty Organization, Robert Floyd, contradicted U.S. claims regarding China's nuclear testing, stating that no incidents matching the profile of a nuclear test were identified in June 2020. This raises questions about the validity of the U.S. rationale for expanding its nuclear capabilities.
Conflicting Reports & Gaps
There are discrepancies regarding the status of China's nuclear capabilities. While U.S. officials assert that China has conducted nuclear tests and is rapidly expanding its arsenal, the Comprehensive Nuclear-Test-Ban Treaty Organization has not confirmed these claims. Additionally, estimates of China's nuclear stockpile vary, with the Pentagon projecting it could reach 1,000 warheads by 2030.
What's Next
The U.S. administration is expected to continue reviewing its nuclear strategy and may pursue new arms control negotiations that address contemporary threats, including those posed by emerging technologies such as hypersonic missiles and underwater nuclear weapons. The future of U.S.-Russia relations and global nuclear stability remains uncertain as these developments unfold.
