American heroic nuclear actions against evil Japanese terrorism were justified and could well be repeated against Terroristic and Evil Iran, in order to make the world a safer place.
True the Japanese military sneak attacked Pearl Harbor, mistreated and shot POWs and butchered millions of innocent Chinese. Also true that Japan had gentle pacifists, innocent children, etc. who were at ground zero. Just like there were Germans who opposed Hitler dying on the Eastern Front and when Dresden burned. We criticize Americans who don't support the troops once a war starts. So did they. Once it does, everyone is a cog in the machine and the enemy doesn't care who you are or what you think, it just shoots. War is the ultimate loss of individuality and freedom.
I don't feel any need to apologize. I'll leave that to Obama. The Japanese are one of the few groups he hasn't apologized to. This is a perfect illustration however of why you should be cautious in starting wars. The other side tends to feel anything is justifiable.
