We aren't in a defensive posture AT ALL.
You only assume so because the media isn't handing you the facts. However, CSPAN often shows briefings from the Defense Dept., and from Commanders in country, which I watch. They also issue press releases which are often posted here by ragtimecowgirl and others.
We are forward leaning every minute of every day. The most extensive operation involved our re-establishing a semblance of security in Mosul, and that got some publicity. But we are doing it countrywide, in every sector. We kill many, we capture many and hold for interrogation to get intel, and we are deep in Zarqawi's terror network as well as the Ba'athists. We take out weapons caches 24/7. (Don't expect these diffuse operations to resemble the massive assault on Fallujah where the enemy had massed and dug in over the very large town.)
Also, ours and Iraqi snipers are doing the Lord's work, every day, over and over and over and over and over...
If I know this, you can know this. But it takes some doing, as you will not get this picture while waiting for the media to spoon feed it.
Well, you make good points. It looks as if the perpetrators of the rocket attack may have been captured. I just get angry when our people keep dying.
