Well, the other Iraq connection, of course, is the fact that the bombers were Iraqis. Now that Missus Bomber is singing her heart out, it will be interesting to see if other connections to other groups turn up. (Like, who's paying for all this--Saudis, maybe? or someone else?)
re: Now that Missus Bomber is singing her heart out
I would be surprised if she knew a lot about the whole plot. Seems their MO is to keep everyone in the dark about what's going on and tell each person involved no more than they need to know to get their part of the operation completed. I remember it came out after 9/11 that most of the hijackers had no idea the plan was to fly the planes into the WTC. Talk about a 'good news', 'bad news' scenario. "This is your leader speaking from the flight deck. The good news is that we have taken over the aircraft. The bad news is that I intend to fly it into a building, killing all on board, including you! Surprise!"
