Source: I'm Russian too.
Current Russian society has proven incapable of self-management as well as incapable of responsible management of such a large territory and military force including nukes. I suppose that as a result Russia, similar to Germany after WWI and WWII, may be broken up with limits on military force, giving up nukes, and other restrictions. Very probably losing that key place in UN Security Council. In short - Putin with clear permission from the whole society, save for a few brave souls, blew up any last chances for Russia to be a great country. (note: Putin is counting on China's support here agreed upon in exchange for Russian support in the future Taiwan takeover, yet that senile moron completely misses that once things go wrong in the Ukraine invasion - and they will - China will be the first to use the chance to get rid of that aggressive nuclear powered neighbor and to replace it with a docile client state comprised of the Far East part of that former neighbor)
