On Tuesday, the White House announced the decision of the United States to stop sharing nuclear data with Russia. As reported by "Voice of America", such an exchange took place for several years, as stipulated by the SNO-3 agreement. A representative of the US National Security Council, the decision to stop the exchange of information was made in response to Moscow's statement to stop Russia's participation in the treaty.
On February 21, 2023, Vladimir Putin announced that Russia would end its participation in the SNO-3 treaty, which limits the deployed strategic nuclear arsenals of both sides. Putin stated that Russia is not withdrawing from the treaty completely.
Signed in February 2011, extended in early 2021 and 2026, the SNO-3 treaty limits the number of strategic nuclear warheads that both countries can deploy. The parties also established mechanisms for checking compliance with the agreement. As part of this agreement, the United States and Russia exchanged data on the status of their nuclear strategic forces, the Voice of America notes.
According to the latest data exchange on September 1, 2020, Russia claimed 1,447 deployed strategic warheads. By February 5, 2018, both the USA and the Russian Federation had fulfilled the restrictions on strategic nuclear weapons established by the SNO-3 treaty. Since then, their nuclear stockpile has remained at or below the established level.
