I'm reading The Strongest Tribe: War, Politics, and the Endgame in Iraq, and enjoying it. The author is obviously passionate about his subject and has spent plenty of time in Iraq, so I'm assuming that he's not talking out of his butt.
I'm learning a fair amount, too. you'd think that with a war going on right in front of my virtual nose, I'd be all aware of at least the locations and dates of the major battles and such, but I was surprised at how much I hadn't encountered before. In retrospect, it makes you wonder how anybody alive in, say, '41-'45 even heard about the China-Burma-India theater of the war, especially in the absence of CNN and the internets.
However, it felt like about once per chapter or so there was a forced campaign ad for John McCain. Seriously. Everything would be flowing along nicely when suddenly, apropos to the narrative or not, would come a quote from Sen. John McCain, (R-AZ).
I checked the publication date. Ah. 2008. That explains it. Can't blame the author for having strong feelings on that topic, I guess.
