That is why I said that the Pakistani and Saudia Arabian regimes, if for no other reason than their own self preservation, have to be brought to the point where they are persuaded to target their own radical mullahs.
You are not born a radical Muslim. You have to be carefully taught. Target the teachers and you target the problem. Israel has been pursuing that policy lately in the case of Hamas.
In the case of Iran, military aid and training to the young Iranians who have spent their entire lives chaffing under mullah rule would adress that particular rat's nest.
