Taking the Iraq issue in a slightly different direction here, but here's something from a CIA analyst at the time of the lead up to that fraudulent war:
On Sunday, March 16, 2003, I watched Cheney on “Meet The Press” contradict our assessment publicly. “We know that he [Saddam] has a long-standing relationship with various terrorist groups,” Cheney said, “including the al-Qaeda organization.” I was basically watching Cheney field-test arguments that we would have to anticipate — and rebut — at CIA. Except instead of asking us questions behind closed doors, Cheney was asserting to the public as fact something that we found to be anything but. I found myself yelling at the TV like I was contesting a ref’s blown call in a football game.
