Bill Roggio. On Day 5, it sounds good. I like the blocking troops to prevent escape.
What kind of war is this, though? We are fighting al-Sadr's army which seems to be a proxy for Iran, and Al Quaida with all of their foreign fighters. This is no longer about Iraq at all. Iraq just happens to be the battlefield. That was the original idea, wasn't it?
If this offensive goes well, watch Americans change their tune about Iraq.
