I assume that's in reference to Ahmed Chalabi. See,

I haven't seen the claim proven before, but, I'm not sure it needs to be: the man was an asset to Iran, knowingly or not.

Thanks. I don't see anything supporting the theory that he worked for Iran before the 2003 US invasion started.

It's also known that the people who worked with G. W. Bush planned the war in Iraq even before 2001 and that W. asked for some link from Saddam to 9/11 to be produced. Then even lacking it, the link was "suggested" to the public. The politicians and media accepted that narrative.

Now claiming "it was all Iran" just doesn't fit.

Yes. For the record, I agree with what you wrote. Actual evidence suggests that American and European intelligence agencies knew that the justification for the war was being manufactured; Chalabi was simply a convenient scapegoat.

The Iranians provided that link. Certainly with a more rational goverment we would never take intelligence information ( for example the famous yellow cake) from a hostile goverment with more restraint. Indeed Hussein through the US invasion was a bluff until the last minute.
