I'm referring to the US, not Isreal. AFAIK the US only hit nuclear facilities, and anyone who would have died there was thus working in a nuclear facility.
Though Iran has been bombing Isreal residential areas for a long time - not directly, but they have been funding all the groups who have been sending bombs, morters, and everything else. Iran just deserves a share of the blame for Gaza genocide as if they were not enabling the attacks, Isreal would not be as interested in such attacks. (how much is not knowable, but there is a share for sure)
it is possible for two opposing sides to be evil. If one evil is oppressing you that is the one you fight against but that doesn't mean you support the other. It is even possible for the worse evil to not oppress you as much.
