The neocons are basically out. It's the Cheneyist unilateral imperialists duking it out with the career security-defense-foreign policy technocrats like Gates, and winning. The neocons are cheering on sidelines and providing nice little public relations eye candy.

The US choosing "to implement even a fraction of the mobilization of its resources that Germany did in 1941" is a hypothetical that is completely irrelevant to any realistic discussion.

It is relevant because you chose to compare a nation mobilized for total war against one of the world's great powers with one that's chosen not to in a minor war. Apples and oranges. And the word is choice. We've chosen not to because contrary to the conviction that seems to be shared by both the most devoted opponents of Bush and  yourself, it is not all that big a deal in the grand scheme of things for America to lose in Iraq. It is a sideshow. The US has mobilized for war three times in its history - the Civil War, WWI, and WWII, that's it. The Iraq and Afghan wars are costing about one percent of GDP, not twenty or forty. A major power fully mobilized for total war is a very peculiar thing, it completely permeates every aspect of the society and economy; this isn't it. In UK terms think Boer war vs. WWI. Lots of drama, lots of ugliness, lots of people in the country targeted by the great power dying - for them it's the real thing. But for the great power in question it's just a tragic farce. Don't buy the neocon hype.
