When I saw the possible Mousosoui connection, the first thing that went through my mind was that this "kidnapping" was staged and that Berg (who really had no obvious legitimate reason for being in Iraq --i.e, you don't go to iraq to get radio tower construction business when there is more business in the US than you can shake a stick at) thought he was going to participate in a phoney staged kidnapping, but to his surprise, he was the unwilling participant in a real murder. His own. Allah Ahkbar.
Your musings may just be accurate.
The big question that needs to be answered is why was Berg in Iraq? I really don't buy the fact that he was trying to get contracts to build communication towers. You don't do that on your own. You need a crew of 20 or more people and a whole slew of local connections to pull that off. He was apparently there on his own. That doesn't make sense. Especially when (with the cell phone business growing daily) there is more business for communication tower builders in the US than they can handle.
I think his POS com-symp father can answer that question.
This may turn out to be COLLABORATION with the enemy.
Its been over 20 years since i had a client that did tower work but I recall that it was considered too dangerous and inefficient to do any tower work alone. You raise an excellent point about his lack of staffing unless he hired locals.
