Moscow–Washington hotline

The Moscow–Washington hotline (formally known in the United States as the Washington–Moscow Direct Communications Link; Russian: Горячая линия Вашингтон – Москва, romanized: Goryachaya liniya Vashington–Moskva) is a system that allows direct communication between the leaders of the United States and the Russian Federation (formerly the Soviet Union). This hotline was established in 1963 and links the Pentagon with the Kremlin (historically, with Soviet Communist Party leadership across the square from the Kremlin itself).
