I should clarify that Arkin doesn't posit this scenario. Nor do I take it entirely seriously. Colin Powell made a convincing case, in his Security Council briefing last month, that Iraq does have chemical and biological materials stashed away. However, whether they are fully "militarized," whether a successor government will necessarily find them, and whether the officials of such a government might know about them but want to hang on to them for possible use or deterrent value against Iran or other potentially hostile neighbors (which are not necessarily going to turn friendly or pacifist)—these are all debatable questions.
