The first public crack in Australian political elite's repudiation of nuclear weapons since the Canberra Commission, if not the signing of the NPT itself, has come from a surprising source: a former advisor to Gareth Evans and a disarmament policy specialist in the Department of Foreign Affairs and Trade. After a brief, apparently tough-minded tour of the bleak nuclear proliferation policy horizon, Martine Letts concluded a review of post-election security policy options with a call for a Rudd government to consider the strategic circumstances under which an Australian government should 'revisit the nuclear weapons option'. In the light of Australia's almost two decades of secret pursuit of nuclear weapons until 1972, and the understandable residual Indonesian suspicion about Australia's real nuclear intentions, it would be hard to imagine a policy recommendation with greater risk of contributing to the strategic circumstances it seeks to avoid.
