The problem with that is, then Israel would have to live with a Saudi bomb too. Beyond the troubling issues with Iran having a nuke is the fact that the Sunni’s will never allow the Shiites to have the only atomic weapons in the middle east. If Iran gets one, it will spark an atomic arms race which will eventually lead to many of Israel’s neighbors being nuclear armed. That is the real reason Israel may conclude they simply can not allow Iran to build a bomb.
Fair enough, but first it has to be clearly established that Iran has nuclear weapons it could conceivable use in war-that could take up to 5 or even 10 years. Then the Arab states would have to make a decision to start building the nuclear technology and then they would have to start from the ground up in most cases. If it takes the Iranian regime this long to build nukes of that strength, imagine the time it would take the Saudis to build up nuclear weaponry to the point where they are a threat. Remember, we’re talking Saudis, perhaps the most unproductive people on earth.
