This is not a surprise based on what we have seen so far.
Russia is imploding. The scale of the implosion is still yet to be determined. The only thing I think the Russian government could do to make the situation worse is use Nuclear weapons on Ukraine or another ally country.
A few points to support this idea;
1. Logistics win wars. When invading a country you must adequately feed, water and move and support your military's fighting forces. Russia has failed at this.
2. The people of Ukraine have a clear objective from a solid leader - expel the invaders. And a clear cost to losing. If they loose there country will fall. No amount of Russian propaganda will outlast such simple clear objectives.
3. The world has applied its cancel cutler to the economy of Russia. Economic sanction's have reduced the value of the currency and stock market. The people will move to countries where they can have a better life in a more stable economy.
4.I foresees the humanitarian crises in Russia being worse than the one in Ukraine. Russia has a population about 3 times the size ~144m vs 44m. And the people who are feeling Russia will haft to fight against the stigma of being people who lived under Putin.
