They won’t attack US soil but they will make America feel the pain economically. Close the straits of Hormuz, blast Saudi, UAE, Kuwait oil infrastructure and not only that target their water desalination plants and electrical grid then activate their Shia proxies in those countries to plunge those countries into chaos permanently taking oil offline which mean oil at $300 a barrel and higher. Once that happens we are back in 2008 recession territory. Not to mention US troops in Iraq are sitting ducks in Iraq. Can see Iran fire cruise missiles and ballistics missiles against US bases in Iraq and the PMU go full Guerilla warfare which will escalate into all out regional war. Hezbollah and Hamas will start a two front war with Israel. The Gulf States plunge into chaos, Iraq in chaos and the global market in free fall. This is why no one wanted to start war with Iran. It’s not worth it in the end because we do not know how it will end and the cost is to high for a war.
