The last remaining US-Russian nuclear pact is set to expire, marking the end of a half-century of arms control agreements between the two nations. The New Strategic Arms Reduction Treaty (New START) was signed in 2010 by President Barack Obama and Russian President Dmitry Medvedev, reducing long-range nuclear weapons. The treaty has been extended twice since its initial expiration date in 2026. The current pact is set to expire on October 1, 2026, leaving the US and Russia without a formal agreement governing their nuclear arsenals. This development raises concerns about the potential for increased tensions and reduced transparency between the two nations' nuclear programs.
