As of today, February 5, 2026, the world has officially entered a new and uncertain era. The New Strategic Arms Reduction Treaty (New START), the last remaining pact limiting the nuclear arsenals of the United States and Russia, has expired without a successor.
For the first time in over 50 years, there are no verifiable limits on the two largest nuclear powers.
1. What Just Happened?
The New START treaty was originally signed in 2010 and extended in 2021. It capped the number of deployed strategic nuclear warheads at 1,550 for each side. With the deadline passing today:
No Inspections: The mutual "boots-on-the-ground" inspections that kept both nations honest are officially over.
No Data Sharing: The 24/7 notification system regarding missile movements has gone dark.
The "Silent" Build-up: Russia’s Foreign Ministry announced they are "no longer bound" by the limits, while the Trump administration expressed hope for a "better, more modern" deal in the future.
2. The Global Fallout: A New Arms Race?
UN Secretary-General Antonio Guterres called this a "grave moment for international peace." Experts are concerned that without the treaty:
China’s Expansion: Beijing may feel pressured to accelerate its own nuclear build-up to match the uncapped arsenals of the US and Russia.
Defense Spending: Analysts predict a surge in US defense contracts as the Pentagon seeks to modernize the "Nuclear Triad" (subs, bombers, and land-based missiles).
Global Volatility: Intelligence agencies warn that the lack of transparency increases the risk of "miscalculation" during diplomatic standoffs.
3. The Political Battle at Home
The treaty's expiration is already a lightning rod in Washington:
The White House View: President Trump has signaled that the 2010 treaty was "flawed" and didn't account for new technologies like hypersonic missiles. He is pushing for a trilateral deal that includes China.
The Congressional Response: Democratic leaders, led by Chuck Schumer and Hakeem Jeffries, have criticized the lapse as a "preventable danger," calling for immediate emergency talks to prevent a trillion-dollar arms race.
