You're not the bad guys, there's a huge difference between the attack vs Iran and the attack vs Ukraine. Iran is an authoritarian regime which repeatedly said that Israel should cease to exist, has killed tens of thousands of their own people, aims to obtain nuclear weapons and supports 4+ terrorist organizations in the Middle East.
So abducting the leader of one country (against international law) and killing the leader of another country (against international law) is fine?
aims to obtain nuclear weapons
After a certain country shredded a nuclear deal and made it increasingly hard for international organizations to do inspections.
supports 4+ terrorist organizations in the Middle East
Because the US has never supported, funded, and trained terrorist organizations?

In this case, in contrast to Ukraine, it's also possible that both sides are the bad guys.
