If were to focus on degrees of separation from Clinton, I'd probably start with Marc Rich's tie to Oil-for-Food and see where that leads.
I did a teeny bit of research on that very angle about a year ago but I can't find some of my old bookmarks.
There's this from FR: FR STORY SEARCH (OIL FOR FOOD & MARC RICH)
And this one bookmark I still had handy: MARK RICH WAS A 'MOSSAD' SPY FOR ISRAEL (linked to money laundering)
The photo from that web page is strikingly similar in attitude to the Vanity Fair cover of Wilson & Plame, no?
I'm done with these rich creeps for the night. I'm going to sleep. :o)
