If this is true, it is more then obvious that Israeli and Saudi warmongering has nothing to do with nuclear threat but everything to do with obtaining and maintaining regional dominance. One which is threatened by Iran. Should Saudi Arabia actually do this, they will become pariah state in the Muslim world. Shia or Sunni, Iran is first and foremost Muslim country. To attack them, and in cooperation with Israel, no less, is to court disaster. Saudis would lose prestige and standing in the Islamic world.
