Russia will respond with equivalent measures if the United States resumes nuclear testing, Deputy Foreign Minister Sergei Ryabkov declared on December 23, 2025. The statement underscores escalating tensions over nuclear arms control as the New Strategic Arms Reduction Treaty (New START) faces renewed scrutiny.
Ryabkov emphasized that Washington has not yet responded to Moscow's proposal to maintain core limits of the New START treaty after its expiration. The treaty, signed in 2010 and extended in 2021, caps deployed nuclear warheads and delivery systems. It remains the sole active nuclear agreement between the two powers.
Russian President Vladimir Putin previously stated in September 2025 that Russia would honor treaty limits for one year post-expiration if the U.S. avoids destabilizing actions. However, recent remarks by U.S. officials about potential nuclear tests have drawn sharp criticism. Kremlin spokesperson Dmitry Peskov confirmed Russia is evaluating statements from U.S. Secretary of State Marco Rubio and warned of "corresponding actions" if tests proceed.
Analysts warn that renewed testing could unravel decades of arms control efforts, with global security implications. The developments come amid heightened diplomatic friction, as both nations navigate post-New START frameworks.
