Answer:
The statement that Adolf Hitler "wanted not only Europe or the Old World but the whole world" refers to his unquenchable ambition for power and territory. His ultimate aim was to rule the entire world; he was not content to merely conquer Europe or other areas. This term suggests that Hitler had unrestricted ambitions and was prepared to use any means necessary, including going to war and committing atrocities, to further them. It also implies that during World War Two, Hitler's aspirations represented a serious threat to international peace and security.
