Troop surge in Iraq

I'm just flabbergasted that this idea seems to be under serious consideration - sending as many as 30,000 additional troops to Iraq in order to, well, kill all the insurgents. It's beyond my comprehension that anyone in a decision-making position could conclude that this approach, which is essentially more of the same, could succeed. It seems perfectly obvious to me that the problems of Iraq cannot be solved militarily. We tried that for over three years and it's been not only an abysmal failure, but an increasingly abysmal failure. What's that old saying? The definition of insanity is to keep doing the same thing and expecting a different result.
