The song that went through my head when I saw Secretary of Defense Donald Rumsfeld resigned was "Ding-dong the Witch is Dead." I guess he's not going to stick around and let people criticize him over the Iran invasion. This would indicate that we're changing course. Not sure yet, that's maybe too hopeful, but will check around and plumb the blogosphere.
Now that we've admitted what we're doing is not working, the next step is to wise up. While we collectively figure out what that means, I think we should embed Rumsfeld with a Marine unit, one assigned to constantly patrol Ramadi. Wearing a bulls-eye jacket.
