Look, I understand that official policy is that nothing is off the table. I don't expect George Bush to say "nukes are off the table." But I do expect that liberal pundits, who are free to, you know, give their actual opinion instead of joining in the administration's posturing (for good or for bad), understand that nuking Iran is, in fact, bugshit crazy, and would alter the world in ways their most feverish nightmares (and those bedwetters have lots of those) can't come close to conjuring.
