As Jon Stewart noted on yesterday's Daily Show, the amped-up rhetoric around a possible Middle Eastern war has produced some funny -- though mostly frightening -- comments from the three actors. Israel calling Iran a "nuclear duck"? Almost cute.  Iran calling Israel a "cancer"? Not so much. But in the course of trying to mediate the conflict, Stewart realizes that it's not only the electoral calculus of President Obama and Republican candidates that are getting them to talk tough to Iran. As it happens, both Israel and Iran are in election seasons too.
