Concerns Rise Over Nuclear Arms Race as US-Russia Treaty Expires

The expiration of the New START treaty on February 4, 2026, has raised alarms about a potential nuclear arms race between the United States and Russia, as both nations are now free to expand their nuclear arsenals without any limits for the first time in over a decade. The treaty, which initially capped each country at 1,550 deployed nuclear warheads, was extended in 2021 but could not be renewed again. Experts warn that this lapse could lead to increased tensions and miscalculations, especially as China continues to grow its nuclear capabilities. The U.S. administration's approach to future arms control remains uncertain, but the lack of constraints could prompt both superpowers to accelerate their nuclear programs, impacting global security.

Key Details: • New START treaty expired on February 4, 2026, removing limits on nuclear arsenals. • The treaty originally capped both nations at 1,550 deployed nuclear warheads. • Experts suggest the U.S. may need to increase its nuclear warheads in response to global threats. • China's nuclear arsenal is projected to reach 1,500 warheads by 2035 if current trends continue. • Future arms control discussions may need to include China, as emphasized by U.S. officials.
