4) Delegated lying/Team lying:

Iraq was involved with 9-11 hijacker Mohamed Atta, via an Iraqi agent who met him in Prague in the spring of 2001, and thus the Iraqi regime may have participated in some fashion in 9-11. (summary of major, long-lasting propaganda theme)

Comment: For the most outrageous, easily disproved, yet highly effective lies, such as the Iraqi connection to 9-11, sometimes the wise course is to assign personnel far removed from the president to push the lie. That way, the president's credibility won't suffer when the facts - known to the administration months before it stopped peddling the lie - come out. And in a perverse fashion, the man at the top of this disinformation pyramid, the president, GAINS credibility for the disinformation in his own speeches, because commentators will note what a cautious and careful performance it was, given that he steered clear of the not-yet-confirmed 9-11 connection.

The farther out of the loop the designated lie-pushers are, the better: The administration can more easily keep from them the intelligence data that flat-out refutes the lie, which helps those lie-pushers who are more convincing when they THINK what they're saying might be true than when they know for a fact it's not true. For our purposes, whether the speaker believes what he says is irrelevant. What matters is that the administration is consciously deceiving the public.
