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.
Australia in the Korean War
The Battle of Sunchon was an air battle fought near the city of Sunchon on 1 December 1951, 12 Gloster Meteor jets of the RAAF's No. 77 Squadron were attacked by 40–50 Chinese MiG-15s. Despite their Meteors having inferior manoeuvrability to the Soviet-built MiGs, the Australian pilots managed to score their first victories of the Korean War, for the loss of three aircraft. Accounts vary, with the Australians claiming at least 10 MiGs shot down, but Chinese and North Korean sources stated it was only one.On 29 November 1952, US President-elect Dwight D. Eisenhower fulfilled a campaign promise by going to Korea to find out what could be done to end the conflict. With the UN's acceptance of India's proposal for a Korean armistice, a cease-fire was established on 27 July 1953, by which time the front line was back around the proximity of the 38th parallel, and so a demilitarised zone (DMZ) was established around it, presently defended by North Korean troops on one side and by South Korean, American and UN troops on the other. The DMZ runs north of the parallel towards the east, and to the south as it travels west. The site of the peace talks, Kaesong, the old capital of Korea, was part of the South before hostilities broke out but is currently a special city of the North. North Korea and the United States signed the , with Syngman Rhee refusing to sign.
