Comparing US war against Nazi Germany with war crimes Israel is now committing in Gaza is kind of dumb. You don't really know what you're talking about -- genocide is by definition mass slaughter of people based on their ethnic origin and this is exactly what is happening in Gaza now.
> Genocide generally means to try and eliminate a group. It’s not about the total quantity of people killed.
To be exact, it's an effort to destroy a group as a whole, or a _part_ of it:
"The 1948 Genocide Convention defines genocide as any of five 'acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group'".

You can commit genocide even if you don't intend to eliminate the whole group as it was the case with Nazi Germany 'final solution' or 'Vernichtung' policies towards the Jews. Nanjing Massacre by Japanese is a textbook example of genocide, but the Japanese didn't intend to eliminate the Chinese population as a whole - they targeted a part of it and it is still genocide.
Out of 2 million population of Gaza Strip 62,000 were already killed, of these 80% civilians and 30% children (18,500 children!). Add to this intentional starving of Gaza, banning and murdering journalists. If this doesn't conform to the definition of genocide then I don't know what does.
