I believe it.

It's obvious that the Power Doctrine isn't being followed in this war. The differences between deployments now and those of the first Gulf War are staggering.
Especially when you consider that the aim of the first war was to liberate a significantly smaller country, and that Kuwait only had 3 international borders to worry about, Saudi Arabia (allies), Iraq (foes) and whichever border lies halfway across the Gulf.
This time around, along with the smaller force, you have to consider potential foes such as Iran and Syria. Syria has today aligned itself with the Iraqi regime. Iran has stated that it is neutral. But if both countries decided to go onto the offensive, then you could bet that Turkey would also make a land grab. Then Jordan and Saudi positions could possibly cave too. Not a pretty proposition.

Now somehow I doubt that the planners within the military are too fond of a relatively small force being in such a precarious position. I can't believe that this is their preferred approach. However good guided munitions are against fixed or armored targets, they aren't that useful against hordes of fanatics using guerilla style tactics.

That all being said, so far I think that Rummy's gamble is paying off. I think that the progress that has been made is fairly remarkable. All the negativity about progress has come about from public naivity bolstered by Media Mediocrity.
WWI lasted 4 years. WWII lasted 6 years. Vietnam and Korea weren't exactly week-long wars either. War is bloody. People die in them. Typically it goes on for as long as people are prepared to die for their cause, or until all such people are dead. Who would be naive enough to believe that all the fervant long-term supporters of Saddam would change their minds in a week? Or that (regardless of the military dominance) coalition forces could hunt down and kill all of them within a week? Come on.
The media can't deal with that. The big news channels would like the war to be fast and furious. Compelling to watch, with never a dull moment. Preferably broken up into ten minute long chunks, "This segment of The War brought to you by 'SuperSUV - offroading ability to tackle the most demanding of deserts.'" Just how much airtime have CNN, Fox News and the like allocated to *non* war- or terrorism- related news in the past week? 10%?
