Suppose Europeans hadn't "discovered" North and South America until a LOT later, after figuring out jet aircraft, armored vehicles, Gatling guns, napalm, etc.?
Sooner or later the "discovery" was going to happen.
The entire hullabaloo by native Americans is too much - after all, different native tribes fought each other, conquered, enslaved and took over land from others. They didn't see themselves as part of a "native American" race --> they saw themselves as part of the race of their tribe.
Furthermore, we can condemn the killing of native American civilians in the 1700s and 1800s, but the deaths of 90% of the Americans in the 1500s was due to diseases inadvertently brought across by the Old worlders
the gatlin guns, napalm etc wouldn't have killed nearly as many Americans as the germs of Smallpox etc. did
