Answer: Both of these events had a major impact on the world. For WW2, it showed that the Germans needed to be pushed harder than they were at the end of WW1. This lead to the split between west germany and east germany. The Holocaust affected the world too greatly. This shocked the world as they were not expecting this. This lead the UN to pass laws that state that there is a limit to how poorly you can treat your POW's. Also, the treatment of US in Imperal Japan affected this too.
