As Deepti Choubey [2] explains in the Christian Science Monitor [3], the NPT's practice of working by consensus precludes concrete action.   “It’s a massive mistake,” says Choubey, deputy director of the nuclear policy program at the Ploughshares-funded Carnegie Endowment for International Peace [4]. What has become the “consensus” rule means that urgent issues facing the international nuclear regime are often either put off for consideration five years later – or weakly addressed with what she calls a "lowest common denominator document.”  But she sees better prospects for measures updating and strengthening the NPT coming out of this year’s conference.
