"Assassinate Ahmadinajad and then destroy Iran's oil infrastructure"?  Judging from its lousy performance in last summer's Lebanon conflict, Israel's army can't even manage to rescue two measly hostages anymore.  The era of the Six-Day War and Entebbe has long passed as the Tzahal and Shin Bet are stretched to capacity and demoralized.  And although U.S. armed forces are stationed in neighbouring Iraq and could theoretically launch an invasion, they're so ill-equipped, and the American public's stomach for more war is so minimal, that it's not going to happen.

Face facts.  Iran will, unfortunately, get nuclear weapons soon, and there's nothing the world can do about it (I wish it were otherwise, of course).  Israel can only hope that Ahmadinajad  isn't as crazy as he sounds with his "wipe Israel off the map" talk.  Although terrorist leaders like him have no problem sending underlings off to their deaths for Allah, I suspect that Iran's president and mullahs (who are the ones really calling the shots) don't themselves want to die.  Because if (G-d forbid) Iran deploys nukes at Israel, they will get the same many times over and that'll be it for Iran as well.  Somehow I don't think the mullahs would want that;  you don't see them strapping bombs to themselves:  that's for the "expendable" children.
