The Mullahs and crazy Shiite are definitely stronger and should they succeed, it will be business as usual in the middle east. Should they fail, then I would gather there will be an Iran that will have moderates that will still hate Israel and use non violent and clever tactics to create a falistinian state.
If they become destabilized, the shiite money will go against the resistance to restore order instead of hamas, hezbollah, etc etc.
