(1933) United States opens diplomacy with Soviet UnionUS President Franklin Roosevelt tells Soviet senior diplomat Maxim Litvinov in a telegram that he hopes the two countries will “forever remain normal and friendly.” This simple note establishes diplomatic relations between the nations. The US had broken off Soviet relations after the 1917 Russian Revolution.The relations between the United States of America and the Union of Soviet Socialist Republics (1922–1991) succeeded the previous relations from 1776 to 1917 and predate today’s relations that began in 1992. Full diplomatic relations between the two countries were established late due to mutual hostility. During World War II, the two countries were briefly allies. At the end of the war, the first signs of post-war mistrust and hostility began to appear between the two countries, escalating into the Cold War; a period of tense hostile relations, with periods of détente.
