Lol Iran doesn't really "dwarf" Taiwan in power, for one they have basically 0 airpower to speak of. The best I can say for them is their missile forces seem better, but tbh it's not clear if they're actually good or just good on paper, or whether they've invested in the other infrastructure you need to make them work well in a war. It's not a question of whether they can resist or prevail against a US/Israeli campaign, but just how much damage they can inflict on the USN in particular while getting pummeled from the air. Unfortunately, I have a fairly high probability mass on a rather lackluster/anticlimactic outcome where their anti-shipping attacks don't see much more success than the Houthis and both sides sue for peace rather quickly after the conflict begins with nobody really achieving anything meaningful.
