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.
Military history of Australia
As British offshoots, the Australian colonies participated in Britain's small wars of the 19th century, while later as a federated dominion, and then an independent nation, Australia fought in the First World War and Second World War, as well as in the wars in Korea, Malaya, Borneo and Vietnam during the Cold War. In the Post-Vietnam era Australian forces have been involved in numerous international peacekeeping missions, through the United Nations and other agencies, including in the Sinai, Persian Gulf, Rwanda, Somalia, East Timor and the Solomon Islands, as well as many overseas humanitarian relief operations, while more recently they have also fought as part of multi-lateral forces in Iraq and Afghanistan. In total, nearly 103,000 Australians died during the course of these conflicts.
