[RN7]

And the post-war West German government also adhered to the Hallstein Doctrine until 1972 in regards to the legality of East Germany.

And unlike the democratically elected and liberal West German government the German Army was nationalist. They were not Nazi's but they were strongly German nationalist.

Probably more than 7. According to Polish sources as many as one million former German citizens were granted Polish citizenship by 1950. How many were actually Germans, or Germans pretending to be Poles is unclear. In 2002 over 150,000 Poles declared German ethnicity over ten years after the end of the Cold War and the collapse of the Soviet Union. How many ethnic Germans actually lived in Poland before they were forbidden from travelling to Germany and the rest of Western Europe was undoubtedly far higher.
