I think the psy-ops guys were way too overoptimistic; they always are.
The reinforcements now slated for the conflict show where Centcom thinks this is going now. It wouldn't be a stretch to assume these are the units Franks reportedly asked for to begin with, either.
I'm not sure though that the US would have backed away if they had known for certain it was a multi-month operation. And as far as the CIA making up Intel... that's a pretty aggressive charge. I don't think I buy that, given the risk of the truth coming out in the aftermath. Not impossible, but unlikely IMO.
Agree on Saddam. All they need to really rally the Iraqi people, if they are truly on Saddam's side, would be to show him making an innocuous statement that could only be known after the first attack on him. He could come on a praise by name the farmer that shot down the Apache for instance. What a morale boost, I'd think. But... nothing.
