“we’re stacking up insurgents like cordwood”

Is this guy who writes to Andrew Sullivan anywhere near right?

We’re trying to learn counter insurgency, while at the same time, we’re stacking insurgent (the only accepted term at the moment) bodies like cordwood.  They’ve gotten a little bit afraid, and are growing more so every day.  The relatively fast 30k is going to relatively quickly change the picture, in noticeable way, in Helmand and Kandahar.  We’re booting the Canadians out of command of Kandahar City.  Omar’s town.  We’re putting a bright, smart, tough, funny Brit 2 star in charge of RC South, where the battle really matters.

So two questions. Is he right that they’re actually winning — and is what they’re doing right?
