(This is a poster who was banned for this post and banned again later on for racist conspiracy theories - it is his idea of how he would have punished Germany more harshly after WW2)

Take the entirre East German population and ship it off to Siberian labor camps. Have them segregated by gender so the German population eventually dies out completely. Alternatively, you can take the German woman and turn them into slavic breeding machines- have the soldiers rape them and force them to have as many babies as possible. You can adopt North Korea's three generation principle so that there is almost no Germanic blood left or breed them forever as a slave race.
