There was a question about withdrawal. There were some proposals along these lines at the last review conference. If a country withdraws from the treaty, the privileges they gained pursuant to article IV allowing for peaceful uses would have to be forfeited. It would thereby prevent the situation of a country utilizing article IV privileges to develop the wherewithal to have a nuclear arsenal and then withdraw.
I think the failure of the review conference to even get to the substance of reviewing that was shameful. I echo the Secretary General's statement that it was shameful that no final statement was made there or at the summit, which could have addressed this issue.
There is a practical way to address this, and that has been put on the table by major middle power states.
