The Sunni radicals, Muslim Brotherhood, etc. are the biggest cause of attacks around the world.
Hezbollah, the Assads, etc. participated in bombing our own Marines for which there is no excuse, attacks on Jews in Argentina too; that is unacceptable.
But there is no way, what the Shias do compares in the slightest to the death toll and daily terrorist attacks by those in the Sunni religion under the guise of such doctrines as Wahhabism. Saudi Arabia in no way should have a get out of jail card on this all together though the Saudi Prince seems to be a step in the right direction.
