Not even close. Not under a month. Probably not under two. We were in there for 60 days last time (or so -- someone is sure to correct me if I'm wrong) and that was a mission with a more clearly defined, and easier goal.
No way a week.
We're not leaving till we get to Baghdad. You could certainly drive from Kuwait to Baghdad in a week, but I don't think you take it over and declare victory in a week, not without being very cavalier.
Further, if they use chemicals, we'll move very slowly. We're hearing that they're basically going to roll over, but if that's not true, it's going to take longer.
And there's not necessarily going to be a nice neat end when we say its over. Their military certainly isn't as capable as ours, but 50000 guys with machine guns in a city is not easy. Its sounds like our military's worst fears is long drawn our urban warfare. How do fight people blending in with the citizenry in disconnected groups, striking from any location? What if we do roll in, and take over the government buildings or somethig?
My god, that guy in DC with the tractor has been there for two days and that's just a guy in a tractor in a puddle.
We're dealing with hundreds of thousands of Iraqi troops. Even IF they all surrender, the logistics of dealing with that while trying to get to Baghdad will be crazy.
Even when we get close to Baghdad, I think we'd shell the city for days before going in.
Now, I'm just speculating as you were. My speculations aren't based on any vast military knowledge, but we're going into another country and trying to take over their capital. No way a week.
