I think they are trying to compare this action to Gulf War I, in which we got the ground part done in 100 hrs. But they seem to forget that the military was able to do that because of the 30 day pounding the country had already gotten from the air war. We didn't have that this time around, so things are very different. It's a good thing that these journalists with their 'have to have it done immediately' attitudes were't on Omaha Beach. They would have declared defeat for the Allies before the first day was done!
Another point that isn't being made is that in Gulf War I, we didn't even cross the Euphrates River. We were stopped by the UN who said, "That's enough"! We're not being hog-tied by the UN this time, so it is a whole new ball game! We're likely to encounter very strong resistance as we reach Baghdad, unless we can get some definite proof that Sadaam is dead, which I think is the case. If he's gone, folks won't be worried that they'll be punished for giving up and not getting killed for this regime.
