Dan Froomkin
Here he is talking to Sean Hannity:
Hannity: "What did you make of Senator Barack Obama's comments that he would talk to
Ahmadinejad, a Holocaust denier who's repeatedly threatened to blow up and remove Israel from the state -- from the map, the world map, and obviously is pursuing some nuclear capability?"
Cheney: "Well, he is, and I think the position we've taken with respect to that is that we would be prepared to talk when they stopped enriching uranium. Of course, they've never met that condition, so we haven't had talks at that level.
"But Ahmadinejad is I think a very dangerous man. On the one hand, he has repeatedly stated that he wants to destroy Israel. He also has -- is a man who believes in the return of the 12th Imam; and that the highest honor that can befall a man is that he should die a martyr in facilitating the return of the 12th Imam.
"It's a radical, radical point of view. Bernard Lewis once said, mutual assured destruction in the Soviet-U.S. relationship in the Cold War meant deterrence, but mutual assured destruction with Ahmadinejad is an incentive. You have to be concerned about that."
