Origins of the Cold War
Australia's entry into the Cold War came in 1950, when it rushed combat air and sea forces into the Korean War, two days after the Americans did. The Australian Prime Minister received a hero's welcome in Washington. The ANZUS military alliance with New Zealand and the United States was signed in July 1951; it was a plan for consultation and did not involve military planning like NATO. Public opinion in Australia was intensely hostile to Japan after its wartime atrocities, but Japan was now an ally in the Cold War, so Australia's accepted the very generous soft peace treaty with Japan in 1951. Instead of worrying about a resurgent Japan, Australia now worried more about a possible Chinese threat.
History of Australia since 1945
During the course of the Korean War, the Menzies Government attempted to ban the Communist Party of Australia, first by legislation in 1950 and later by referendum, in 1951. While both attempts were unsuccessful, further international events such as the defection of minor Soviet Embassy official Vladimir Petrov, added to a sense of impending threat that politically favoured Menzies’ Liberal-CP government, as the Labor Party pushed centralist economics and split over concerns about the influence of the Communist Party over the Trade Union movement, resulting in the a bitter split in 1955 and the emergence of the breakaway Democratic Labor Party (DLP). The DLP remained an influential political force, often holding the balance of power in the Senate, until 1974. Its preferences supported the Liberal and Country Party. The Labor party was led by H.V. Evatt after Chifley's death in 1951. Evatt retired in 1960, and Arthur Calwell succeeded him as leader, with a young Gough Whitlam as his deputy.
