Hans Blix in the Boston Review:

A year ago the international Weapons of Mass Destruction Commission, which I chaired, presented its unanimous report, “Weapons of Terror,” to UN Secretary General Kofi Annan. The report urged governments to wake up from what Annan has called their “sleepwalking” and revive arms control and disarmament. We often hear warnings that the 1968 Nuclear Non-Proliferation Treaty—the global instrument through which states committed themselves against the acquisition of nuclear weapons and for nuclear disarmament—now risks collapse. The good news is that the world is not replete with would-be violators. The overwhelming commitment to the treaty remains tremendously valuable: Libya and Iraq were both found to be in violation and brought back into observance. In two other cases—North Korea and Iran—the world is actively seeking solutions. For now, at least, there appear to be no other problematic cases.

Still, the dangers are real, and the treaty is under strain.
