What makes you think this?
From 2000 on:
1. Putin have always been at the top or near the top;
2. Being measured formally, the Russian territory increased, and always by the price of the former USSR;
3. Numbers of Russian citizens increased both in Russia and other CIS independent states;
4. Russian trading on the CIS markets is exseeding others several times;
5. All national separating tides inside Russia come to zero;
6. The number of Russian military installations outside its territory grows;
7. "Customs Union" agreement with some states inside CIS is already disbanded national border and customs controls on the formal borders between Russia and Belarus, Russia and Kazakhstan, and this process is going on. Now I can drive my car from Poland (which is both NATO and EU) to Chinese border with KZ, leaving my passport or any other ID home - no formal borders in between;
8. Having no national idea, Russia has yet supported some nations militarily: Serbs once upon a time, Syria now: a behaviour typical for USSR;
9. Putin is an avid friend of China - Josef Stalin, a founder of USSR, has always stated that there is only one way to control entire Eurasia: a friendship between Russia and China.
Enough I think. Right?
