> someone worse

You do not get to decide that. If we allow everyone to invade other countries and murder leaders because they deem those people worse than themselves, the world will be engaged in endless war. Or do you think perhaps deciding who to invade and kill is a special privilege reserved only for your country, which should be emperor of the world?

False dichotomy. There are other ways to deal with Iran that don't involve starting an ill conceived (and illegal) war that kills school children and possibly (probably?) plunges the world economy into recession. It is highly unlikely that the current military action will result in a pacified Iran.

Why do people think that since Iran is evil all actions against Iran are justified?

We can quantify "Who has killed the most children in the middle east recently" and Iran is in a distant third place.

Sovereignty. You only get to hold responsibility of your own citizens, like Jeffery Epstein AND his supporters. You do that right, and then maybe then people will like you as the world police.
