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.
George Blake
The Korean War broke out on 25 June 1950 and Seoul was quickly captured by the advancing Korean People's Army of the North. After Britain entered the war on the side of the South, Blake and the other British diplomats were taken prisoner. As the tide of the war turned, Blake and the others were taken north, first to Pyongyang and then to the Yalu River. After seeing the bombing of North Korea, and after reading the works of Karl Marx and others during his three-year detention, he became a communist.
