War isn't pretty and the things the Japanese did to our soldiers was pretty remarkable. They were brutal not only to us but to anyone they fought. Ask the Chinese and Burmese what it was like under Jap control. We didn't want to have to invade Japan so decisions were made. Those bombs were horrific but ultimately brought the war to an end. It had been predicted we'd loose a million troops if we invaded. Hitler had no problem dropping bombs on London so "he that sows the wind will endure the whirlwind". Or something to that effect.

The Civil War is not much different. It was another time with other ROE. I tend to let it rest in peace. We lost a lot of good men on both sides. As for the rifles left at Gettysburg Who knows what happened in the heat of battle. one thing's for sure the Confederates lost that one and ultimately the war.
