Hah, I'm going with an appeasement theme!
The only explanation for liberals' hysterical zealotry in favor of Obama's proposed open-ended talks with Ahmadinejad is that they seriously imagine crazy foreign dictators will be as charmed by Obama as cable TV hosts whose legs tingle when they listen to Obama (a condition that used to be known as "sciatica").
Because, really, who better to face down a Holocaust denier with a messianic complex than the guy who is afraid of a debate moderated by Brit Hume?
There is no possible result of such a meeting apart from appeasement and humiliation of the U.S. If we are prepared to talk, then we're looking for a deal. What kind of deal do you make with a madman until he is ready to surrender?
Will President Obama listen respectfully as Ahmadinejad says he plans to build nuclear weapons? Will he say he'll get back to Ahmadinejad on removing all U.S. troops from the region? Will he nod his head as Ahmadinejad demands the removal of the Jewish population from the Middle East? Obama says he's prepared to have an open-ended chat with Ahmadinejad, so I guess everything is on the table.
Perhaps in the spirit of compromise, Obama could agree to let Iran push only half of Israel into the sea. That would certainly constitute "change"! Obama could give one of those upbeat speeches of his, saying: As a result of my recent talks with President Ahmadinejad, some see the state of Israel as being half empty. I prefer to see it as half full. And then Obama can return and tell Americans he could no more repudiate Ahmadinejad than he could repudiate his own white grandmother. It will make Chris Matthews' leg tingle.
There is a third reason to talk to dictators, in addition to seeking an ally or as part of a policy of Mutually Assured Destruction.
