United States–Soviet Union relations

United States–Soviet Union relations. The diplomatic, military, and ideological interactions between the United States and the Soviet Union defined much of the 20th century, evolving from wary non-recognition to a fraught World War II alliance and finally to a global superpower rivalry known as the Cold War. This contest, characterized by nuclear brinkmanship, proxy conflicts, and ideological competition, structured international politics until the dissolution of the Soviet Union in 1991. The relationship's legacy continues to shape the foreign policy of the Russian Federation and the United States in the contemporary era.

Early relations and the Russian Revolution

The United States initially withheld diplomatic recognition from the new Bolshevik government following the October Revolution of 1917. President Woodrow Wilson authorized limited military intervention in the Russian Civil War, with American Expeditionary Forces sent to Archangel and Vladivostok alongside other Allied contingents. This period was marked by deep suspicion, as the Comintern advocated for worldwide communist revolution, directly challenging American capitalist ideals. Formal relations were not established until 1933, when President Franklin D. Roosevelt extended recognition, hoping to open trade and counter the rising threat of Imperial Japan and Nazi Germany.

World War II alliance

The German invasion of the Soviet Union in June 1941 transformed the relationship, as the United States included the Soviet Union in the Lend-Lease program, providing vast quantities of trucks, aircraft, and food. The Grand Alliance was solidified at major conferences, including the Tehran Conference and the Yalta Conference, where Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin coordinated strategy against the Axis powers. Despite cooperation, tensions simmered over the opening of a Second Front in Europe and post-war plans for Eastern Europe. The Red Army's advance into Central Europe and the United States Army's race to secure German scientific assets, like those at Peenemünde, set the stage for post-war rivalry.

Cold War

The collaborative war effort collapsed rapidly after Victory in Europe Day, leading to a prolonged Cold War. Ideological and geopolitical competition was declared in Winston Churchill's Iron Curtain speech and formalized in the Truman Doctrine and the Marshall Plan, which the Soviet Union countered with the Molotov Plan and the Cominform. The Berlin Blockade, the formation of NATO and the Warsaw Pact, and opposing sides in the Korean War cemented the bipolar divide. The rivalry escalated into a dangerous nuclear arms race, punctuated by crises such as the Cuban Missile Crisis and the construction of the Berlin Wall. Proxy conflicts erupted globally, from the Vietnam War to the Soviet–Afghan War.

Détente and renewed tensions

A period of détente in the 1970s saw efforts to manage the rivalry through diplomacy and arms control. Key agreements included the Strategic Arms Limitation Talks (SALT I), the Anti-Ballistic Missile Treaty, and the Helsinki Accords. High-level summits between leaders like Leonid Brezhnev and Richard Nixon symbolized this thaw, exemplified by the Apollo–Soyuz Test Project. However, détente unraveled in the late 1970s and early 1980s due to Soviet actions in Afghanistan, the Polish crisis of 1980–1981, and the United States deployment of Pershing II missiles in Europe. President Ronald Reagan labeled the Soviet Union an "evil empire" and initiated a major military buildup, including the Strategic Defense Initiative.

End of the Cold War and dissolution of the Soviet Union

The ascension of Mikhail Gorbachev in 1985 brought a transformative shift with policies of glasnost and perestroika. A series of summits with President Ronald Reagan and later George H. W. Bush led to landmark treaties like the Intermediate-Range Nuclear Forces Treaty and reduced tensions. The Revolutions of 1989 in Eastern Europe, the fall of the Berlin Wall, and the non-interventionist Sinatra Doctrine signaled the end of Soviet hegemony. The failed August Coup of 1991 against Mikhail Gorbachev accelerated the collapse, leading to the recognition of Belarus, Ukraine, and other republics. The Cold War formally ended with the dissolution of the Soviet Union in December 1991, recognized by President George H. W. Bush and leaving the United States as the world's sole superpower.
