We are fools if we attack Saddam at his strong point (Baghdad) with simple ground forces. Much better to lay seige - or even better attack his weak points and undermine his will to fight.
A MOUT campaign accomplishes little and risks much. To hear generals talk about it in this article should be a warning flag to anyone.
Perhaps the whole country will "surrender" or call themselves the equivalent of open cities. Perhaps Hussein-dependent elements will hole up in Tikrit, and that's where an urban battle may occur.
Just my guess.
