I think it's pretty safe to say that the lyrics to Hammerhead are partially inspired by the war in Iraq. I'm not going to pretend I know exactly what was going through Dexter's mind when he wrote that song. But it would be pretty hard to imagine that during a time of war, Dexter wrote a song about a gunmen who thinks he's doing right but he's actually doing wrong, yet it has NOTHING to do with that war. I know they've said in interviews that it's not really about the war, but all that means is that the subject matter isn't directly about the war. That doesn't mean it's not inspired by the war, and I personally think it almost certainly is. Maybe he was only thinking about certain aspects of the war, like missions where the soldiers are likely to kill innocent civilians. But I know that song has got something to do with the war.
When they said "sit down", I stood up.
