US and Russia No Longer Bound by Nuclear Limits

Kuala Lumpur,El Sky Media In a historic shift for global security, the New START (Strategic Arms Reduction Treaty) — the last legally binding nuclear arms control agreement between the United States and Russia — has officially expired, leaving both nations with no formal limits on their nuclear arsenals for the first time in over 50 years.

The treaty, first signed in 2010 and extended in 2021, capped each side’s deployed strategic nuclear warheads and delivery systems, while also providing key transparency measures like on-site inspections to build trust and reduce risks.

What This Means

• With the expiration of New START, both superpowers are free from treaty-mandated limits on the number of nuclear warheads, missiles, bombers, and other strategic systems they can deploy.
• United Nations Secretary-General António Guterres warned the lapse marks a “grave moment for international peace and security,” emphasizing the increased risk of nuclear instability and miscalculation in a world without these legal guardrails.
• While Russia and the U.S. continue diplomatic discussions and military-to-military talks, no formal successor treaty has yet been finalized.
• President Donald Trump has publicly expressed interest in negotiating a “modernized” treaty — potentially involving China — but critics say the expiration could accelerate a new nuclear arms race if not quickly replaced by a robust agreement.

Global Reactions

• Russia’s stance: Moscow says it now considers itself free of legal nuclear restrictions and will take decisions based on national security needs.
• UN concerns: Worldwide leaders and experts warn that the loss of transparency and verification measures increases the potential for misunderstandings and rapid escalation in times of geopolitical tension.
