That is a taboo subject. But despite the acrimony over the failed intelligence in Iraq, there is an irony that in 2000 the 4 autocracies thought by the Clinton administration most likely to be stockpiling either chemical weapons or infrastructure for future nuclear weapons development were Iran, Iraq, Libya and North Korea. Whatever the circumstances, it may prove true that by 2008, 3 of the 4 do not any longer have such capability, and the 4th–Iran–is the focus now of near world efforts to ensure that it doesn’t–more encouraging at least than the fact of Pakistan’s nuclear acquisition in the 1990s.
