C Military historian Peter Edwards
Many assumed that Australia’s involvement in the Vietnam War had been at the instigation of, and under pressure from, the United States. The idea that Australia had been pressing to become involved, that it had been ‘looking for a way in and not a way out’ as Menzies put it in April 1965, took some time to be recognised ... With the benefit of half a century’s hindsight, some of the old arguments take on different nuances. Vietnam was not an example of fighting ‘other people’s wars’; in the minds of Menzies and his principal advisers, it was a matter
of getting the United States to fight a war for Australia’s security. Paying a premium for Australia’s strategic insurance with the United States was not of itself wrong, but should have been handled with a great deal more care.
