The articles, if you've read them, from Italian police, Asia News, Japan Today, state the bonds are real or "perfect forgeries". To make a perfect or even passable forgery, you've got to have access to a real one. How many people do you know that even know a "$1 billion Kennedy Bond" exists, much less have seen one, much less can take one home to make copies?
"Only nations have that kind of money"? How about the multi-billions from CIA drug deals, multi-billions from Halliburton/KBR over charges, multi-billions from unmetered Iraqi oil rip-offs? Not to mention "blood diamonds", off the books arms deals, etc. A lot of those deals were and are run by the same people, you know.
Bernie Madoff, allegedly by himself, stole $50 billion, in less than a decade.
$134 billion is only 2 1/2 Bernie Madoffs worth of criminal proceeds.
And if the bonds were fake, it would be all over the US news. It would be the equivalent of an economic A-bomb.
If they're real, (and I think they are) it would be the equivalent of a political A-bomb, which is probably why we aren't hearing squat about it on the US news.
Go ahead - search CNN, Blomberg, MSNBC. There's not one word about it, and the arrests were a week ago already. Why do you suppose that is?
