The part I don't understand is how did Wilson know about the forged documents ahead of time?
"The part I don't understand is how did Wilson know about the forged documents ahead of time?"
The same way Bill Clinton knew. Bill told Blair that if he stuck with "Bush's war" he was going to lose his re-election. Bill had to have known something about the Wilson affair at that time - in order to make that threat to Blair.
I'm not sure of the time frame, but I believe it wasn't too long after that statement by Bill, that the Wilson affair erupted all over the place.
If Bill Clinton knew - Hillary knew - and if Hillary knew - how involved was she in helping to set up this whole event?? She was friends with Pflame and Miller, and I'm confident the Clintons had their "cronies" at the CIA and the FBI.
And .. it was Clinton who went all over the world prior to the Iraq war trying to drum up support AGAINST THE U.S. RESOLUTION and AGAINST THE WAR. When Blair and Bush went ahead with the war - without France, Germany and Russia, I believe the plan was hatched to discredit Bush/Blair and the war - during a time of war - which is about as close to treason as you can get.
