I don't think that Hiroshima and Nagisaki count as genocide. The definition is "the deliberate and systematic extermination of a national, racial, political, or cultural group". While we deliberately bombed them, we were not doing it to exterminate them or because of their race, nation, political situation, or culture; we did it because they were at war with us. There are many theories on why the USA should or should not have used the bomb. I believe that we should have. Either way, if this counts are genocide, does Pearl Harbor? What about any wartime bomb? I see how one could think of it as the killing of innocent civilians, though (yes, I've read "Hiroshima" by John Hersey). As for answering the question, I cannot recall any serious attempts to hold the USA accountable for genocide. There may have been some minor attempts, though.

They don't classify as genocide, but they sure were unnecessary, horrific acts :( Genocide is the systematic, very deliberate annihilation of a specific cultural, racial, political, religious, etc group For example, the Holocaust was the genocide of Jewish people in Europe, for the US's action to classify as genocide, they would have needed to bomb a very large number of Japanese cities, probably even after they'd surrendered... What they did was horrific, but it wasn't genocide, it was completely unnecessary, and unjustified, but it wasn't genocide :( (And no, to my knowledge, no one has ever tried to take the US to trial over those bombings)

Thanks for the excellent question. No, nobody has. If you even suggested it to most Americans they would just look at you witha puzzled expression and say-"but we were helping the people in Laos-how can they be so ungrateful?"

Hiroshima, Nagasaki and Laos combined never amounted to over a million people, the question should be "has anyone ever put Communist Russia and China on trial for their atrocities to their own citizens killing 60,000,000 million of them between them just for not thinking the "Marxist" way? More then every death caused by WW2... http://users.erols.com/mwhite28/atrox.htm

No, they never have. They do not fit into the definitions of genocide as we know it .

Definition of Genocide on the Web: * The deliberate and systematic destruction of an entire people who belong to one racial, political, cultural or religious group. The attacks on Laos and Japan were acts of war, not an attempt at eliminating a branch of our species. Thus, the trial would have to be dismissed.

Regarding the Japanese cities. I suggest you get yourself a copy of the book, "The Rape of Nanking." Take a look at the photos the Japanese soldiers took of their handy work. Then find something useful to protest about.

The world has not decided to do so,though it would be in their rights.The USA committed a form of genocide when then dropped bombs on millions of innocent people.It was unnecessary and uncalled for and needs to give Japan retribution for its untold act of violence.Also Canada did the same when dropping bombs on the city of Dresden Germany during the second world was killing 100's of thousands of innocent people.

Why stop there? Let's revisit every war in history of mankind and make sure every country is held responsible for killing innocent people. Here's a list from Wikipedia.

That's a good question. Exculpating the U.S. of genocide would by definition exculpate a whole lot of other people who've been considered genocidal: Saddam Hussein, Slobodan Milosevic, Idi Amin, etc., since even they never attempted to utterly exterminate an entire ethnic group. On the other hand, if one adopts the very broad definition of genocide that the UN used in its 1948 Convention on the Prevention and Punishment of the Crime of Genocide: "any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such: killing members of the group; causing serious bodily or mental harm to members of the group; deliberately inflicting on the group conditions of life, calculated to bring about its physical destruction in whole or in part; imposing measures intended to prevent births within the group; [and] forcibly transferring children of the group to another group" then it becomes clear that those dictators were guilty. But so are the US, UK, Israel, and almost every other country at one time or another. My personal view is that Hiroshima, Nagasaki, Tokyo, Dresden, Laos, Vietnam and the like were not strictly genocidal in the usual sense the term is used, but that they are still heinous war crimes on the level of Saddam Hussein and other tyrants.
