Coercing Iran Stop it, says Paul Pillar

Ken Pollack’s article in these spaces about policy toward Iran is worth close attention, mostly because he explains clearly some of the reasons that the use of military force as a supposed solution to the problem of Iran’s nuclear program would be folly. Not only would such a resort to war elicit a wide assortment of reactions by Iran and others that would be highly harmful to U.S. interests; such an act would be at least as likely to speed up Iranian development of a nuclear weapon as to slow it down, given subsequent Iranian determination to redouble efforts in that direction. There are additional detrimental consequences that could be mentioned, but the ones Pollack adduces are enough to show that this course of action would be a disaster for the United States.
