It’s tough because for decades, we (Americans) have been told how cruel and evil the Iranian regime has been - torture, mutilation, suppressing women, you name it. I have no reason to believe that was all a lie. That alone is not justification to start an overseas war, but it does allow some level of acceptance for taking out these monsters. And then add on the nuclear threat (if legitimate). It’s also tough because in the modern day, it’s near impossible to know what is and is not real. There is no comparison to prior Middle East conflicts where that was true (at least to this degree). So at least for me, it’s a mix of being glad these evil dictators are being eliminated, hopeful their nuclear capabilities are being destroyed, seeing the devastation on the general population, not knowing what is real, and generally being anti-war. Very strange times.
