AFGHAN WIGS. Rob, I liked your piece defending the worthy invasion of Afghanistan. If I can make one criticism: early in the piece you ask, "If we�ve come to the conclusion now that the Iraq invasion was a mistake, then how do we evaluate the disaster on the other side of Iran?" I don't see how a reevaluation of Afghanistan follows from the disaster in Iraq, except as something of an academic exercise. For the reasons that you ably explain, these are really different wars, with really different objectives and fought for really different reasons.
