A yes, the Annual Argument over Hiroshima and Nagasaki.
A few points.
1) The bombing was probably unnecessary because Japan was already looking to surrender.
2) The entry of the USSR into the Pacific War probably had a lot more to do with Japan's ultimate surrender, as it opened up the war on a couple more fronts they weren't ready for.
3) Much of the handwringing we do every year is probably more of a reflection on us. Yes, WE'VE had to live with generations of the specter of nuclear annihilation, duck and cover, Mad Max movies, and so on. To the people at the time, the war had already dragged on for six years, 70 million had died, and to them, the A-Bomb was just another weapon in a war that had seen so many new and awful weapons.
4) In many ways, we should be HAPPY that Hiroshima had happened. Imagine a world where these weapons were stockpiled, and we had no idea what they did to people.
