And I think it's too early to tell, but Mark Bowden's analysis of The (now happening) Battle of Baghdad seems, viewed in retrospect, a little gloomy. We'll see, though. I'm not one of the guys who is wringing his hands over the fact that this war has lasted (GASP!) 20 whole days thus far.
Seriously, I saw that DAY 20 banner on CNN yesterday, and I was amazed. In 20 days we've circled the capital and are systematically marching in and out as we please. In 1940, Paris hadn't yet been declared an open city on Day 20. And that's the prototype for a quick collapse.
American military might. It's impressive.
