I definitely do not believe the Iranians when they say their intentions with their nuclear development are totally peaceful. That being said, I would not support a preemptive strike by Israel. It would cause too much outrage in the Arab world and would probably not be that effective.
If a strike or strikes should become necessary, we should do it, hopefully with UN or at least NATO cooperation.
