Answer:
The Final Solution refers to Nazi Germany's planning and implementation of a systematic genocide of Europe's Jews during World War II.
Anti-Semitism was part of the Nazi ideology that ruled Germany since 1933. Originally, Nazi Germany planned to resolve the “Jewish question” by expelling Jews from Europe. When this proved virtually impossible to implement for such a large population in pre-war conditions, reflection on other possibilities began. Jews were initially executed by shooting. However, this proved to be an unnecessarily ineffective means, and killing children by shooting in particular was too bad a place even for trained SS soldiers. In the end, mass killings with gas and the destruction of bodies by incineration were ultimately chosen as the ultimate solution for purely efficiency reasons.
Unfortunately, the Allies did not take a real knowledge of the situation until they began to discover the different extermination camps such as Auschwitz. In other words, during the course of the war, the allies saw Hitler as a tyrant, an oppressor and a dictator, but not as the real perpetrator of the most aberrant massacre in history. However, it is necessary to highlight that the Allies did not have any kind of responsibility in this event, since the decision to carry out these massacres was purely and exclusively of the Germans.
