It's going to be smallpox. In the Caribbean, yellow fever, smallpox wiped out sometimes 100% of different populations. So the populations that are left in the Americas, that 10%, just think about what your culture would be like if we wiped out 90% of you, right? You don't have people that are working in the crops. You don't have enough people to fight off enemies. And there's going to be huge consequences because their arm is going to be down. Now when the Europeans come, and we think about the Europeans against the Native Americans and how the Europeans were so superior, well, if you wiped out 90% of a population, I probably could have taken over as well.
