Fear is destroying the fiber of Israel...making it more and more right wing and militarized. At the same time, Iran is an existential threat...that's not debatable. Sure the IDF would make mince meat out of their Revolutionary Guard, but I don't think it'll even come to that. Iran has hundreds if not thousands of missiles aimed at U.S bases and Israel which, by themselves are not too powerful, but together will cause a lot of infrastructure destruction in Israel and the Global supply of oil. Israel's economy would be shattered, all we have is the ARROW missile shield defense but that is not very effective, and EXTREMELY expensive. We would of course destroy their (already destroyed post Iraq-Iran war) war making capabilities quickly, but that won't be enough... A nuclear armed Iran would be disastrous both for the Arab dictators (sans Assad) and for Israel.
