We faced the same problem in Japan in 1945.
The difference being that, whatever else his faults, Hirohito did care about the Japanese people. You think Osama and the Mad Mullahs give rat's patootie about all the "Martyrs" that we'd be making. Secondly, the Japanese revered their emperor as a God, and if God said to stop fighting and cooperate with the Yankees, then they did just that, with gusto. The Mad Mullahs don't have that kind of personal authority, and wouldn't issue such "orders" in the first place, no matter how many of those they've brainwashed die. (A better approach might be selective strikes against those mullahs, including their Mosques, where ever they might be found.)
