Despite the undoubted significance of possible Australian participation in a five power Commonwealth security arrangement centred on Malaysia and Singapore, considerations of an Australian nuclear force, the presence of numerous American bases in Australia, and Australian policies towards a Soviet naval presence in the Indian Ocean, the public debate on Australian foreign policy continues to centre on the Indo-China war. This is understandable, for not only has Australia been supplying material assistance to the counter-revolutionary forces in that area since 1953, military advisers since 1962 and a task force since 1965, but the commitment has focussed critical attention on those strategic assumptions which have dominated Australian foreign policy for the last two decades.
