It seems like a lot of organizational skill and logistical support would be required to carry out the types of attacks we're seeing at the frequency we're seeing them. I find it hard to believe that this is being done by a lone guy working out of Fallujah. Instead, it seems to me to be pretty obvious that a well organized entity is at work, perhaps Iran or Syria.

I would tend to agree with you and that's kind of a scary thought. Not that I would agree with you but that another country or countries might be behind this.
