There has been huge quantitative movement, but there hasn't been the consistent unequivocal commitment to getting there. I agree with you fully that proliferation is bad in all respects.
Dr. Blix described it very well. He said that nuclear weapons are very bad in the hands of irresponsible states, but nuclear weapons themselves are bad in anybody's hands, and a state that could be responsible this year may in the future not necessarily be responsible.
We're not by any means justifying proliferation by the failure of the nuclear-weapons states to move rapidly. We're only saying that to strengthen the non-proliferation regime means to fulfill the threat-reduction steps that will also reduce the threat and give more security to the nuclear-weapons states. The same process of reducing the threat will also strengthen the non-proliferation regime and move us in the right direction, so these are not really opposed concepts.
