Why does desire matter?
I have a desire to kill billionaires. Does that matter? Should I be tried for murder? No, because I'm not actually going to kill anyone.
Putting violent desire on the same moral plane as actual murder victims is a silly thing to do.
Do you think that if the socioeconomic positions were reversed, the current Iranian regime would have been any better than the US, or Israel?
In this hypothetical the details really matter, but in general I think no, the current Iranian regime would not be better.
I think a better hypothetical would be that, if the US never did a coup in Iran and overthrow their democratically elected government, and the socioeconomic positions were reversed, would Iran be better then? I think yes.
