Not in our lifetime. Unless some PDB or other secret FINDING describes it that way (it will then become PUBLIC of course) there is NO WAY this will ever be stated publically and as you can tell from our tactics in Fallujah and elsewhere, POLITICS, once again and as is USUAL, dictate the happenings on the battlefield and HENCE, the results.
Is there any doubt that we could pacify any city, or country in a matter of hours IF our Military commanders were told, "PACIFY NOW" using extreme measures as you GENERAL see fit. The ONLY requirement is to LOSE as few of OUR men doing it and KILL as many as the ENEMY as possible. Civilian casualties are not a concern and do this as quickly as possible.
Well it is only a dream it will never happen that way again. WWII is the past and we are so far ahead of everyone, Militarily, that COMPASSION has entered our strategic and tactical military thought process. We never do a bombing run UNLESS and UNTIL all nearby possible civilian casualties are eliminated or minimized to the extent that puts our troops in MORE dangerous situations than would otherwise be necessary.
It stinks, but it is a fact and as frustrating as it is, it will NOT change, unless or until we suffer an NBC attack on our shores.
I disagree with your assumption.
It will take several major hits in our homeland before we decide on War.
