New START treaty expires, raising concerns about a new nuclear arms race

theconversation.com — February 1, 2026 at 08:01 PM UTC

The last remaining US-Russia nuclear treaty, New START, is set to expire this week, ending nuclear restraint between the two powers. The treaty, which limits deployed strategic nuclear warheads and launchers, expires February 4, with no extension negotiations underway. Its lapse could accelerate a global nuclear arms race. The New START treaty, signed in 2010, included verification and inspection mechanisms. Russia suspended some aspects in 2023 but committed to numerical limits.
