The threat from Iran is nonexisting. Iran has not the ability to harm Israel in any existential manner. That is why Barak doesn't believe that even 500 Israelis will be the causalty of a war today. When it comes to nuclear ability, Iran hasn't a nuke today and hasn't made a decision to make one and even if it should make one it will never use it. And yes there have been 2600 inspections by IAEA of Iranian nuclear sites including even Parchin. Iranians are not stupid and are far from irrational. There are 30,000 Jews happily living in Iran today with representation in parliament. Watch the youtube videos if you don't believe it.
