You give me a way to prove someones military history that is so secretive that records don't exist YJ, and I'll happily play along.
I really couldn't care less about whether you buy it or not, to be honest. I've been much closer to him for a much longer period than you and I have been battling, and as might be expected, put a lot more weight in his words and experiences. A true veteran who can't even enjoy the courtesy of getting a pat on the back for his service. That, YJ, defines a hero, whether you wish to believe his story or not.
He owns a bakery very near here, if you ever get to the midwest look me up, I'll happily arrange a meet and greet between you two and you can ask him all the Osama stuff you wish, he's quite a plethora of knowledge.
