For the record, I think Hiroshima and Nagasaki were both entirely justified. Same with firebombing Dresden, Tokyo, etc. It would also be entirely justified for anyone to nuke Moscow, or any other Russian city. Sadly a lot of kidnapped Ukrainian children would die in such an attack. But that's an acceptable loss to try to end that invasion. If you've got a nuclear weapon handy, we can test your theory re: "things they'd never do themselves"...
