If nothing else, he overlooked one of the prime criteria of Project Management - define your scope.
When deciding to go into some place known as 'The Graveyard of Empires' such as Afghanistan, it might be useful to clearly define A) what do we expect to accomplish? and B)_how do we know when we're done?
Though we had some semblance of cassus belli for the invasion of Afghanistan, and none whatsoever for the invasion of Iraq ("We know he has Weapons of Mass Destruction - we have the receipts!"), both endeavors were exercises in cluelessness.
If the goal of attacking was to bring a nation to ruin, I suppose it was a success. Unfortunately we were among the nations ruined by the adventurism.
I wish we didn't insist on leading with our chin.
