US and Russia Withdraw from New START Treaty, Raising Nuclear Concerns
On february 5, 2026, the United States and russia have formally withdrawn from the New Strategic Arms Reduction Treaty (New START), the last remaining nuclear arms control treaty between the two nations. This decision marks a significant escalation in the deterioration of US-Russia relations and raises concerns about a renewed nuclear arms race.
Background of the New START Treaty
The New START treaty,originally signed in 2010 and entering into force in 2011,limited the number of strategic nuclear warheads,intercontinental ballistic missiles (ICBMs),and submarine-launched ballistic missiles (SLBMs) that the US and Russia could deploy. It was extended in 2021 for five years, despite increasing tensions between the two countries. The treaty allowed for inspections to verify compliance, a key component of arms control agreements.
