Like the Germans who lived in the East when it was liberated from the Third Reich? Defend them and explain why they should have been given citizenship by the nations "liberated" by the Soviets.
Sure.

Those Germans had lived there, in many cases, since the middle ages. If you're talking about the handful of Germans who moved there during the war, they were no more citizens than the German garrisons in those areas.
Now, if Germany had occupied those nations for generations, I would be in favor of German colonists receiving citizenship when the German empire fell apart.
Like the Germans forced out of Silasia at gun point, where they've been living for 1000 years?
Many Volksdeutsche (ethnic Germans) do indeed have citizenship of Eastern European countries for your information.
The comparison, in any case, is not a good one. Unlike Russians in Latvia, German communities in nEastern Europe - the so-called Donau Schwaben - grew up slowly over many many hundreds of years. Their immigration was piecemeal and encouraged by the native kings and princes for economic reasons (they were farmers and merchants)
