....there are Wessis who state in some forums that they would give Eastern Germany to Poland
Nonsense. Just create East Germany again, and sign Friendship and Security Agreements with Russia and China.
As Russians, we will pump you so full of cheap energy it will be coming out of your ears. The Chinese will open their entire market to you, with minimal barriers only enjoyed by the likes of Russia and Mongolia.
Within twenty years, the emaciated West Germans will come begging for you to admit them.
We would ask, only, that you provide some of your machine-building know-how, and excellent expertise in complex optics.
