No one can predict future events. We do not know if Iran reaches its goal that it will use nuclear weapons towards another country that is just speculation. For some reason many people believe they can control others. This is not true. If one really wants to accomplish ones goal they will. For a lot of people to say that Iran would use nuclear weapons against others might be true, but then again it might not. The same goes for people securing their home and persons. We buy guns and ammo to protect our homes. We do not go out into the streets and look for people who might break into our homes. If Iran really wants to attack Israel, they will.
