I dont see on what basis will they fracture ?
In Europe, country can only fracture on national basis, and today Russia is mostly populated by Russians, up to 81% ..
Other nations, if we exclude tiny Caucasus regions, are spread and mix out and are completely irrelevant ..
I understand that for someone who is living in country like the US its hard to understand Europe nationalism, and how strong it is but i garanity you that there is 0% chances of some Russian, German or French to separate from their own state because of one reason or the other .
20. century Russian Empire and USSR, who both have 50-60% of non Russians, were very prone to disintegration on etnich or religious basis, but Russia in present times is completely different story ..
Time period 1991-1999 is probably the worst in Russian history if we ignore the world wars ..
Russians were litaterly on ther knees, they just lost Chechnya conflict with drunk Yeltsin on power, military didn't even fly their warplanes, strategic bombers were just standing on airfields, submarines and ships were rotting in the harbors, oil was 10$ for barrel, salaries were like below 100$, unemployment was huge etc.
Google "Economic history of the Russian Federation" if you are interested, i can go like this till tomorrow, but if you think that 2000. were good times for Russia lol you can not be more wrong .
i don't really know what is your definition of power, but if we talk about political power its most likely like this in 2017.:
(1) The United States (no.1 military)
(2) Russia (no.2 military)
(3) Germany (no.9 military)
(4) China (no.3 military)
(5) France (no.5 military)
(6) The United Kingdom (no.6 military)
(7) Maybe Japan (no.7 military)
You wont see Japan stoping the Azerbaijan Armenia war, you dont see them in negotiations over Iran nuclear program, North Korea question (ok maybe there), Syria war, Ukraine conflict, Isis, strategic nuclear treaties, they dont have permanent seat in the united nations security council etc.. i just don't see them as a major world political power at all, i don't get it where do you find them relevant to world politics ?
