They definitely can defeat US intervention and cause a lot of damage to their position in the middle east, but I keep mulling over what they can win. They can certainly force them to abandon some bases closer to them and maybe even keep a toll of some kind of the strait, but I don’t think it’s realistic to expect to force the US to abandon the middle east and even Israel. At that point they’d need to actually move troops or something to do that, which isn’t realistic.
Maybe just force them to give up sanctions? And make the bomb?
In case of a nuclear attack on Iran Iran can hit back by destroying all the nuclear power plants in the region, some parts of europe, and perhaps even hit some in the empire too, so such attacks aren’t as “free” as they were against Japan. Not that the regime would let possible consequences get in the way of attacking Iran harder.
