You dont understand how anti-Iran these mullahs are. Khomeini said he would burn Iran to the ground for the sake of the Islamic world, the same Islamic world that is surviving on Jew debts, that same Islamic world that cheers Israel capturing Syrian, Palestinian, and Lebanese lands because "Assad was bad" lol.
So yes, while firing barrages of missiles at Israel may have helped Iran gain favor from right-winged Europeans who abhor Jews (and Americans by extension), there is just nothing there for Iran to gain from it. Many Europeans love Russia too because in their mind Putin is fighting the Zionist funded jew Zelensky but it means nothing in the end. The same EU will put more sanctions on Iran because right-wing majority white population has zero power. Zionists control both right and left in US+EU politics.
