The Fourth Rail has some analysis of the fighting going on in western Iraq in Operation Matador in which three Marines and over 100 insurgents have already lost their lives.
Perhaps one of The Fourth Rail's more interesting observations is this:
Belmont Club has maps and additional details.
The war is gradually, maybe even quickly, evolving from an indigenous insurgency to a foreign invasion. This is going to make it much harder for the radicals on the loopy Left to claim that the insurgents are just Iraqis patriots trying to expel foreign infidels. We're confident, though, that somehow they'll find a way to turn these alien fighters into naturalized Iraqi citizens.
