when did the cold war alignment of britain and the united states versus the soviet union begin
Origins of the Cold War The Origins of the Cold War involved the breakdown of relations between the Soviet Union versus the United States, Great Britain and their allies in the years 1945–1949. From the American-British perspective, first came diplomatic confrontations stretching back decades, followed by the issue of political boundaries in Central Europe and political non-democratic control of the East by the Soviet Army. Then came economic issues (especially the Marshall Plan) and then the first major military confrontation, with a threat of a hot war, in the Berlin Blockade of 1948–1949. By 1949, the lines were sharply drawn and the Cold War was largely in place in Europe.[1] Outside Europe, the starting points vary in the late 1940s or early 1950s.[2]
Cold War Enunciation of the Truman Doctrine marked the beginning of a US bipartisan defense and foreign policy consensus between Republicans and Democrats focused on containment and deterrence that weakened during and after the Vietnam War, but ultimately persisted thereafter.[74][75] Moderate and conservative parties in Europe, as well as social democrats, gave virtually unconditional support to the Western alliance,[76] while European and American Communists, financed by the KGB and involved in its intelligence operations,[77] adhered to Moscow's line, although dissent began to appear after 1956. Other critiques of the consensus policy came from anti-Vietnam War activists, the Campaign for Nuclear Disarmament and the anti-nuclear movement.[78]
