Russia will end up like Yugoslavia, divided along ethnic religious groups.
Where did you get the idea that some ethnic religious groups lived in Yugoslavia? Yugoslavia consisted of republics completely different from each other that are independent today, each with its own language, tradition and level of development.
What has very great similarities between Yugoslavia and Russia is the way in which first the Serbs, and then the Russians (brothers by blood, faith, and desire to kill innocents) had the idea on which they began their bloody campaigns. Serbs wanted a greater Serbia and claimed they were going to fight against Nazism and fascism in Croatia, later in Bosnia and Herzegovina, the Russians are doing the same today in Ukraine.
The methods they use are identical, because all that remains after them is scorched earth, destroyed cities and villages, and tens of thousands of killed civilians. However, the Serbs lost the war when the Croats strengthened their military to the point that they realized they could no longer do anything to them.
A scenario in which Ukraine strengthens militarily so much that it will be able to liberate its occupied territories is very likely, especially if we see how motivated they are about it. All these brainwashed Russians who write nonsense here about Ukraine attacking Russia and the like might get a chance to defend their country on the battlefield, unless they're cowards hiding behind their keyboards.
