Ofcourse, Terrorists warned USA civilians aswell still they stayed in USA.;..those people in the WTC towers asked for it X_X.

what I ask you is how many AMERICAN CIVILIANS did the japanese kill? then compare that to the number of JAPANESE CIVILIANS americans killed with the bomb. to see who the was the biggest monster? Please understand I am under NO CIRCUMSTANCE trying to justify what the japanese did in pearl harbor because that was terrible too, but there is a huge difference here and if you think about it you may see it, the japanese attacked a military base. the military know that if there is war there is a chance that they may die and they are trained speacially for that. Instead who did america attack? the children who were in schools, moms that were cooking, people INNOCENT people doing regular things, now you may try to justify this and say that it was neccesary, but the tought of what was done and the consequences make me sick. Let me put it this way, if your watch on the news that someone got into a school a killed lets say 10 5 year old kids you would probably be repulsed by the idea but america did even worse. and to the people that think that 300,000 was nothing compared to the amounts of deaths in the war, is your life not a big deal? or you family´s life? every life is unique and irreplasible. just 1 person dead would be a terrible crime. Now if america had killed 300,00 japanese soldiers I wouldnt mind so much because as I said soldiers are trained for just that, but what they did cannot be forgotten. Now, were the japanse good? Hell no, they killed millions of chinese and tortured thousands too, and were just as bad if not worse than the nazis. I guess what I´m trying to say that everyone in war is a monsters too because war brings the worst in people. picture this. the USSR were the first to get to berlin and they saved many jews, but they were just as bad, they raped thousands of german women and killed many. Back to the topic I dont there is any justification to attack the innocent, the americans were just as bad as the others because they didnt attack the military but the innocent. and that is just unforgivable.

Now you may satinize my comments if you want

there were worse things that happened and the US warned people to leave the towns.

So I guess that justifies it then

Actually they didn't with the Atomic bombing, it's odd because usually they did drop flyers warning the civilians of bombing raids. It's also widely believed America just wanted to see what atomic bomb would do, using the Japanese as guinea pigs. It's harsh but it also the reason why they really didn't bomb Hiroshima and Nagasaki before they dropped the nuclear bombs.

Well, first things first, you should've pressed enter. Hard to read paragraph is hard to read. 

Anyhow, I agree with you. The atomic bombs were a horrible thing. 

But the argument I'm making is that an invasion of Japan would've been worse. 

Look, back then Japan was not intending to surrender. Another option to win the war with Japan was too invade it. Now, you obviously know the kamikaze. The Japanese were willing to give their own lives to kill U.S soldiers. Now imagine a whole of Japan that would not surrender. Japanese civilians would've definitely fought back a U.S. invasion, and most likely killed. 

Adding to this, the soviets had weeks prior declared war on japan and were ready to mount offensives. Japan would essentially become another Korea or Germany after the war with it being split between capitalists and communists. 

And finally, I searched it (one wikipedia, though), and the Allie's death toll of one million was only referring to Allied troops who got killed. Imagine who the Japanese death toll would have been.

There is no such thing as "necessary evil". There is simply evil or god. Calling something as necessary evil will not justify it. It was maybe necessary from your point of view because your American. But intentional killing of millions civilians is nothing more and nothing else then genocide.
