It occurs to me...

...that if an Iranian leader with great visibility--say, Mahmoud Ahmedinejad--had been videotaped singing "Bomb, bomb, bomb, bomb bomb America," (which, yes, sounds foolish but you get the idea) it wouldn't be taken lightly here. Fox News would treat it as a sign that the regime was unstable and dangerous and, voila, we'd allow it to bring us one step closer to war.

I don't know what the reaction to the McCain video has been in Iran. But since they're the weaker nation, if their reaction is anything other than passive acceptance of our dear senator's foolishness, then our reaction to their reaction will determine whether this becomes a big deal or not.
