I don't know when his aunt died, but what if his uncle-in-law was still in Oklahoma before moving back to Mosul?
OK, so that would establish an interest in Iraq when we occupy it. Does that mean Bush invaded to sate Nick Berg's curiosity?
No, so the only REAL coincidence is the Moussaoui connection. And since the FBI didn't even bother to detain Berg after 9/11, I'd say it's not likely there was anything to it.
You're good for comic relief on this thread, and are doing a good job keeping it bumped up. Keep up the good work.
