As an eastern-european I'd rather join a 2nd Soviet Union than Merkel's "Europe".
Good choice. Russia (or the Eurasian Union) will remain as a Christian majority nation in the long-term future, while Merkel's European Union will become Muslim majority in a matter of few decades. So make up your mind.
Yes, at such a pace, the European Union may soon collapse and it will be better to join Russia if it is not seized by China.
