So you're trying to argue that the U.S. is actually the bad guys? Perhaps the good guy/bad guy dichotomy simply isn't that useful. The U.S. did terrible things during the war, and there is no excuse for that. The U.S. is also only directly responsible for a very small fraction of the total civilian deaths in the war, and for none of the genocidal deaths. The world today is a better place for the Allies having won the war, and the U.S. effort is a major reason that happened. It's silly for Americans to cling to the narrative that we're always making good choices, that's obviously untrue, but I think it's equally silly to argue that the totality of what the U.S. did during World War 2 was worse than anything any other country did, especially worse enough to make the U.S. the bad guys. But I don't think you need to call them the bad guys to acknowledge that they committed atrocities.
Good question! Genocide is not just another word for mass-murder. It is defined as killing with the intention to destroy the targeted ethnic group/culture/religion completely. That certainly wasn't the American plan anywhere during WW2. Germany's actions were obviously genocidal, and Japan's actions in China arguably were as well.
Haha yeah, I was reluctant just because I don't personally know much of that particular history and it was hard to imagine that the Japanese intended to commit genocide against all of China, but I agree that genocide is fair classification of their actions.
