Nazi Germany did wipe out almost every last jew in the areas they controlled, in the ~4 years of the Holocaust. 90% of Poland's 3 million jews were killed.
After centuries of supposed genocide, the US Native American population is over 6 million, which is probably similar to what it was before colonization.
The biggest massacre I'm aware of¹ in the US is the 146 killed at Wounded Knee in 1890. The US had complete military superiority, and could have killed everyone at will, but mostly didn't. If this is a genocide, it's a very poorly executed one.
What makes this a bit confusing is that first contact did often result in 90% of the native population dying in both North and South America. But that was an unintentional and unforeseen effect of old world diseases hitting new world populations that had completely unprepared immune systems. Maybe the biggest "random" event in world history!
