Based on 30 years of experience with the Iranians they will give you 100 words. Trust only one of the 100.
You don't have any communication between the Israelis and the Iranians. You have all sorts of local triggers for conflict.

What is wrong with the Iranians in addition to the nuclear bomb? This is the only country on Earth in the 21st century that has renewed imperialistic ambitions. They really want to become the hegemon of the Middle East in an age that gave up imperialism.
