Roger Ailes redefines realism:
I see myself between the Hudson River and the Sierra Madres. I do not see myself at the Beverly Wilshire Hotel or Le Cirque here in New York. Those are people who aspire to different things. They’re the chattering class. They’re the people who think Ahmadinejad wants to have a chat with us and that we haven’t been reaching out to him enough. No, actually, Ahmadinejad wants to cut our heads off and blow us up with nuclear weapons. He’s made that clear. There is something about those people that makes them think, “Oh, he’s just kidding.” No, he’s not kidding. He wants to kill us.
I tend to be a realist about things.
Emphasis added. The Iranian regime is many things, most of them severely unpleasant, but it hardly poses an existential threat to the United States. The principle beneficiaries of any pretence that it does are actually Ahmadinejad and his cronies who are flattered by a frothing sillyness that is almost hysterically unrealistic.
