By contrast, Iran’s only allies are its terrorist affiliates in Lebanon, Gaza, and the Houthis. Those guys can’t do much to help. China and Russia (see above though) are willing to do business with them but don’t really give a crap about Iran surviving.
Anyway, the US and Israel can keep degrading Iran’s military and “government” by dropping bombs (or better, drones) on them every week for a decade and it won’t really be a big deal for the former. Iran though will not be better off for it, I’m pretty confident. (Other than their surviving religious fanatics will be even more suicidally devout.)
