erhm..... 

Differnt situations you cant really compair?

One is a military base, with tiny amount of people (like 2000 people died).

vs main city(s), where hundres of thusands of people died, and millions where made sick by radiation poisoning.

You understand that "hundres of thusands" (potentially millions of sick people) > "2000 ish" right?

You also understand in war, in general you attack military with military, and leave the civilians alone.

The A bombs, where targeted at hurting civilians.

I dont think he should apology for others mistakes or choices.

However the question you raised is just wack.

Correct me if I'm wrong but wasn't the second A bomb dropped after japan surrendered? Not sure how that isn't a war crime bordering on genocide. But I may be wrong

Welcome to war? US gave Japan time to surrender they did not because of their pride at the time. They brought it upon themselves and their people because of their actions. Sorry not sorry.

No, Japan didn't wanted to surrender after the first one was dropped. So the US dropped the second one on Nagasaki and after that they surrendered.

Although people have claimed that Japan was in the process of trying to surrender, I believe the claim that they had effectively surrendered already (instead of, say, offering some kind of deal that would have been unacceptable, ergo war continues) is actually completely incorrect.  You may also have heard somewhere that the second bomb was completely uncalled for because they WOULD have surrendered after just the one bomb but hadn't had time to make the decision yet.  But in reality there was a lot of pushback from the military against calls for surrender and desperate speculation that the USA only had the one bomb that they had already used.  They might have surrendered anyway but it was not "obviously yes, no question" even with what we know now let alone what the United States knew at the time about Japanese decision making.

If a city had been A-bombed after the USA was already aware of Japan surrendering then it would have been among the worst war crimes of the war.  Genocide?  I guess that would depend on the motivation for committing the war crime. 

I disagree with having people apologizing for something they are blameless in because it's an empty gesture. It just pours salt into it. If a person was directly a part of what happened then I'm all for them apologizing. It's not something their descendents or fellow countrymen should have to apologize for especially if it happened a long time ago. 

Even if it is war, there are still rules. Probably never heard of "crimes against humanity".

And just to go ever further, this kind of ignorance makes me really angry. 

I can still remember when the tsunami hit fukushima a lot of US citizens posted on Facebook that this was the revenge for Pearl Harbor. It just shows how fucking stupid people can be.

The atomic bombs were aimed at ending the war. Japan didn't want a quick or easy end to the fighting so the US went with a terrible option but it resulted in far, far less death.

I don't believe in apologizing on behalf of decisions made by a different group of politicians decades ago and during a war nonetheless. Besides, as terrible as those bombs were, the actual ground invasion that was scheduled to take place in late 1945 would have been far worse.
