Those wars included World War 1, World War 2, the Korean War and Vietnam. Did Australia have to involve itself in these wars? Did the lives of these young Australians have to be taken?There is a high degree of complexity in this question.

Aussie troops were soon sent to different parts of the world to help the British and other allied countries. It was not until late 1941 that they were recalled in order to defend the homefront. Darwin had been suddenly attacked by Japanese planes and small enemy submarines had snuck into Sydney Harbour. Darwin was repeatedly bombed...
