People in Russia can swallow poverty, injustice, corruption no problem. But they cannot swallow war defeat. This tsar is weak, need a better tsar who wins.
Ukraine is getting heaps of weapons and decimating Russian logistics and command and control with it. Enough that even the Russian propaganda is complaining about it.
The subthread was discussing what would happen in the event Russia was forced to abandon the invasion, if you want to object to discussing that possibility as reasonable, the place is several posts upthread.
(Also, Western aid delivered since the major escalation by Russia this year has been several multiples of Ukraine’s annual defense spending and a sizable fraction of Russia’s annual defense spending. It is not “weak” arms supplies by any reasonable standard.)
