A quick victory over Russia is crucial to the integrity of the Russian state or otherwise instability will continue to increase. I am already hearing about gangs harassing funerals and hospitals.
With oligarch forming PMCs, we might even see a period of warlordism.
Russia could of course get out of Ukraine today, but we do not control Russia. Let's hope that defeat for Russia will be soon instead of later.
In any case, state collapse is an unlikely possibility but one that couldn't entirely be discounted.
