lolz....some crazy stuff there.......The US has never sold any B-52s to Israel.
Just look at his Wikipedia page. Ben-Menashe is really good at weaving tall tales from his tradecraft knowledge. Back in the late 1980s and early 1990s, he fooled a lot of journalists into thinking he was real.
Eventually the press caught on he was talking bigger stories than he could deliver and realized he was stringing them along. That was back in the pre-internet days when journalists covered stories instead of creating them.
In big organizations, the people at the top need little people around them to do the small stuff. Ben-Menashe was one of the little people near the top. He wasn't the top, by being near it he knows how to fake it.
