But tell me how exactly you are going to conquer a city without city fighting...

D'oh!

You don't.

Explain how Saddam will run a city of 5 million without a constant supply of food, power, communications, water, medical supplies and fuel.

All internal stockpiles are easily identifiable and easily targetted. I will leave it to your apparently great military mind as to exactly how that can be.

Saddam doesn't have to "run" the city. He only has to survive long enough to make it costly, to costly to the US in terms of men, machines and money and key to all Republics: popular opinion.
