There are reports of Russians not fighting "to the death" because the Russian army is mostly made up of conscripts so they didn't volunteer into the army but where dragged in and so they don't see a good reason to be in Ukraine. There have been reports of massive draft dodging and Russians not very happy about Putin's war. The Rouble has collapsed which, just like the Turkish Lira, will cause hyperinflation and eventual systematic economic collapse. Putin has turned Russia into a State that will be isolated and the many Russians who enjoyed travel outside may end up just like the Soviets.
