After World War I, the social contradictions in Germany became increasingly acute, and all kinds of sufferings surrounded the German people, which easily caused people's dissatisfaction with the rulers. To this end, Hitler had to do something to achieve the following goals: 1 Divert people's attention, so that people will not bring their dissatisfaction with social reality to the rulers, but also let them vent their pressure appropriately.

2. Stimulating national cohesion, people with the same goal will naturally unite, which has many hidden benefits for the country.

3. Effectively solve the influence of Jews on the economy, increase the ruler's ability to control the economy, and at the same time relieve the administrative and financial pressure to a limited extent.

Imagine how good it was for Hitler to kill Jews. How can you resist killing them?
