Soviet Union did not expel the indigenous peoples and then move Russian ethnic people to occupy the land after World War II.

In the history of the Soviet Union, the practice of exiling indigenous peoples and relocating Russian settlers to occupied territories was widely utilized to consolidate Soviet control over new territories.

For example, successful cases include the regions of Eastern Ukraine, Kaliningrad, and Crimea.

However, in East Germany, despite Stalin's attempts, similar measures were not implemented. Even if he desired to expel the indigenous population, he failed to do so.

There are several main reasons for this:

1. International pressure and moral constraints: The Berlin Crisis demonstrated that Stalin's actions were limited under pressure from the international community and Western countries.

Western countries took action to protect the people of West Berlin, and such humanitarian actions gained widespread support internationally.

Therefore, the Soviet Union had to lift the blockade of West Berlin. Under international supervision, Stalin found it difficult to undertake similar expulsion actions to avoid triggering larger-scale international protests and condemnations.

2. Public opinion and social repercussions: The Berlin Crisis was not just a political issue but also a humanitarian one.

The Soviet Union's brutal actions provoked global outrage and condemnation, making people aware of Soviet atrocities.

If Stalin had taken similar actions to expel the indigenous population of East Germany, it would likely have sparked larger-scale international protests and opposition, which would have been detrimental to a country trying to maintain its international image.

3. The uniqueness of East Germany: East Germany had different historical and political backgrounds compared to other regions.

Stalin might have realized that the indigenous population of East Germany was more organized and resistant, and expelling them could lead to greater resistance and challenges.

The region had a deep-rooted German culture and tradition, and the indigenous people likely had a stronger attachment to their land, making them more likely to take action to defend their homeland.

4. Considerations for political stability: Stalin may have also had political considerations in East Germany.

The stability of East Germany was crucial for the Soviet Union, and Stalin might have been concerned that taking radical actions could disrupt the political stability of the region, leading to more turmoil and uncertainty, which would not be in the interests of the Soviet Union.

In conclusion, although Stalin attempted it, he failed to implement similar relocation actions in East Germany due to factors such as international pressure, public opinion, the uniqueness of the region, and considerations for political stability.

Stalin's political decisions were often influenced by various factors, and he may have realized that taking similar actions in East Germany would entail greater risks and challenges, leading him to abandon the idea.
