For the Bush administration, openly hostile to a UN solution, the answer has been talk or bomb: negotiate with states that already have a weapon (such as North Korea), or to take preemptive strikes against those that do not (such as Iraq). US officials say acting outside the treaty has produced results: it brought Libya back into the fold in 2003, when Colonel Muammar Gaddafi decided to scrap his weapons of mass destruction.
Yet this approach contains the risk of opening the path to nuclear blackmail, which is how North Korea has coaxed the West into compensating the hermit state in return for concessions on its nuclear programme.
As with Iran, negotiations have stalled on the North Korean insistence that it has the right to a civilian programme, if it renounces nuclear weapons.
Iran, an NPT member which insists on its treaty right to pursue nuclear power, has been infuriated by US co-operation with India, a non-member of the NPT, which blasted its way into the nuclear "club" in tit-for-tat tests with Pakistan in 1998.
