Actually I was wrong. I have documentation that Berg was hired by several firms in the US to do that work. When I posted that I was under the impression that what Berg was doing was rebuilding damaged towers, but what he was doing was reinstalling broken and stolen equipment. You can do that solo, but it is very dangerous work.
My reasearch since yesterday has convinced me that Berg had the technical expertise to do all aspects of radio transmission engineering. As far as I can tell, his engineering credentials were not fake, they were Bona Fide.
I still have a lot of questions, but at this point, I am convinced that Berg was fully capable of doing whatever job he was allegedly bidding on in Iraq.
As far as Nick Berg's "left wing" ties, they seem to go to his father and I have seen nothing that directly ties Nick Berg to any left wing radical organizations. His father is a lefty, but then when I was Berg's age, my father and I did not have the same political views. I was the socialist commie and my father was a Birch Society Right winger. But that would not have stopped him from investing time and money in a company that I owned.
Well, glad to hear we were wrong. :)
