Now if some from these special force roam around Baghdad, eliminating some members of execution-squads and officers who still resist and sowing paranoia, the defender's cohesion will completely break down. Let these die-hard Iraqis frantically look out for elusive Americans targetting them. Let them worry about traitors among their ranks, ratting out to Americans.
As in Afghanistan, instead of chasing elusive local defenders, let local defenders chase elusive American hit teams. Turning the table, so-to-speak. We are playing guerrillas against those who want to play guerillas against incoming American troops.
This way, their best military plan will become totally useless.
