One of the oddest criticism of Gillard's move to sell uranium to India is that she is breaking with the non-proliferation approach of the Hawke and Keating governments, when actually it's the exact same strategy: trading uranium in return for influence in setting safety standards.

This (lucrative) approach, of selling uranium while insisting on world-class safety standards, is the reason Australia became 'a global champion of non-proliferation'. Without it, Australia's many other achievements — extending the Non-Proliferation Treaty, passing the Comprehensive Test Ban Treaty, undertaking the intellectual leg-work for global disarmament via the Canberra Commission and the International Commission on Nuclear Non-proliferation and Disarmament — would not have been possible.
While Australia has around 30-40% of the world's uranium supply, there are too many other suppliers for a ban by Australia to have a significant effect. India is a case in point. Should Australia ban uranium sales outright, as some critics want, our likely influence would be akin to New Zealand's. Our southern neighbour took a more principled stand in the 1980s on nuclear power, but has, undeniably, had significantly less effect on global proliferation norms and conditions than Australia.
That's not a function of size, but strategy. While the Prime Minister has argued the economic benefits, and Rory noted the security benefits, it is through deals like this that Australia, a remote middle power, can best influence non-proliferation standards worldwide.
