Our past errors were not so much dissolving a scattered Iraqi military or even de-Baathification, but rather giving an appearance of impotence, whether in allowing the looting to continue or pulling back from Fallujah or giving a reprieve to the Sadr militias.
So, yes, send more troops to Iraq — but only if they are going to be allowed to hunt down and kill vicious and sectarians in a manner that they have not been allowed to previously.
This surge should be not viewed in terms of manpower alone. Rather it should be planned as the corrective to past misguided laxity, in which no quarter will now be given to die-hard jihadists as we pursue victory, not better policing. We owe that assurance to the thousands more of young Americans who now will be sent into harm’s way.
