The French were behind it with the help of the wonderful Italians.
What do you want to bet Ms. Plame had something to do with it? How about dear Mr. Wilson? After all, there are quite a few (ahem) French connections there.
"In investigating the background of former US Ambassador, Joseph Wilson IV and the outing of his third wife Valerie Plame, I did what everyone did and used public information and his own words to look into his life. This is the very thing that led to the eventual outing of Valerie in the first place. Be that as it may, it seems that his second wife Jacqueline is quite a woman of mystery. Very little is known of her and it seems to all who look into her life that she shares one at least as intriguing as Valerie, at least that was before Valerie was outed as an agent in the employ of the CIA.
As a former French Diplomat, the last known location of his second wife Jacqueline was in Gabon under the employ of the President Omar Bongo's daughter, Pascaline Mferri Bongo. Between August and November 2000, she was paid $60,000 to write letters to the office of National AIDS policy at the White House. That’s quite a lot of money for simply writing a few letters. She’s reported to have worked for them at least through November of 2000 and is currently whereabouts unknown. I want to take this opportunity to remind everyone that Joseph Wilson IV was the US Ambassador to Gabon from 1992 to 1995...........
