Make no mistake: Russia seeks to restore much of the old Soviet Union.
As an economic and ultimately political union in the form of the Eurasian Community. It would be a serious rival of the EU.
Right now a more limited union exists between Russia, Belarus and Kazakhstan.
The larger planned community will embrace most of the post-Soviet space.
This was all but inevitable after the Soviet collapse in 1991.
From what I have seen on foreign TV, it appears there is massive Ukranian support for stronger EU ties and weaker Russian ones.
