Using nukes

The concern over Iran getting a nuclear weapon is not that they would send an ICBM over New York but that it would prompt other countries, particularly in the Middle East, to acquire nukes. With Iran’s long-time pledge to irradicate Israel, the clock would be ticking for the next all-out nuclear war. The US would not fear Iran anymore than North Korea. North Korea is aware that if they fired off a missile toward the US, before it landed, two hundred nuclear weapons fired from an Ohio class submarine a few miles off the coast would hit with an average power of 300 kilotons each, more than 15 times larger than the bombs used in WW 2. This would mean the destruction of the 200 largest cities in North Korea in less than 30 minutes. They use their nukes to keep from being attacked not to use offensively against the US. Iran is a different story for some experts see them as willing to lose their country to achieve their objective of destroying Israel. This is based on their religious beliefs. This is from Google AI: The ruling elite of Iran’s Islamic regime, guided by a Shiite apocalyptic vision, believes that destroying Israel is a theological imperative to hasten the return of their messiah, the Twelfth Imam (Mahdi)
