I see nothing at all wrong with being conflicted about Hiroshima. Any sane person would regret the necessity.
But to discuss Hiroshima without mentioning Nanking is grossly irresponsible.
We didn’t just up and decide to bomb Japan because we were evil people. We were working to bring to an end a political system that most definitely needed to be ended.
In the end it probably saved more Japanese lives, because millions would have perished in an invasion.
