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
As in the United States in the early 1950s, allegations of communist influence in society saw tensions emerge in politics. Refugees from Soviet dominated Eastern Europe immigrated to Australia, while to Australia's north, Mao Zedong won the Chinese civil war in 1949 and in June 1950, Communist North Korea invaded South Korea. The Menzies government responded to a United States led United Nations Security Council request for military aid for South Korea and diverted forces from occupied Japan to begin Australia's involvement in the Korean War. After fighting to a bitter standstill, the UN and North Korean signed a ceasefire agreement in July 1953. Australian forces had participated in such major battles as Kapyong and Maryang San. 17,000 Australians had served and casualties amounted to more than 1,500, of whom 339 were killed.
