As an aside, could you actually set up a more perfect propaganda distribution system than Wikileaks, if you were so inclined. Establish broad sensibility and lack of bias, them start spoiling anything that doesn't fit your narrative. The leakers would hardly be in a position to point it out, so there's no-one to say you're not still even handed.
Not saying that's what happened, or if it did it was the plan from the go, but who knows?
