The US and Iran cannot both lose this war, those two things literally cannot be true at once. The US winning entails them gaining a vice grip on the entire Middle East and the total collapse of civil society in Iran. Iran would absolutely not come out of that with a progressive government, we would see the entire country splinter and fall into the hands of warlords.

Iran winning entails the expulsion of the US military from much of the Middle East, and it severely degrades the empire's ability to protect Israel and enable the extermination of the Palestinian people. It is extremely crystal clear that Iran winning is the best outcome for all of humanity.

Also how the fuck did you even come to the conclusion that Iran fighting in this war is theologically motivated after the US started the war by murdering their head of state and hundreds of school children in an unprovoked attack during negotiations?
