The Vietnam War was the dominant foreign policy issue during Holt's term in office. He was a strong supporter of Australian involvement in the war, which had begun in 1962, and accused its critics of adopting a "Lotus Land" attitude. As well as citing Australia's SEATO obligations to South Vietnam, Holt justified the war on the grounds that Australia was morally obligated to "resist communist subversion and aggression" and "defend the right of every people to choose their own social and economic order". He held that "unless there is security for all small nations, there cannot be security for any small nation".
