They can’t even take half the country, and you think they’re going to take all Eastern Europe? Oh, please…
Russia wasn't able to take half of Ukraine because…
…of the brave Ukrainian fighters (yeah, some of them may be a-holes)…
…backed by the western (read: US) support…
…which you quite clearly oppose.
That is the greatest revelation of this war, the fundamental weakness of Russia.
The second greatest is just how vicious Putins government is likely to be in exploiting what they perceive as their opponents weaknesses.
The third is the extent of Russian ambitions, which creates an inherent hostility towards all its neighbors.
The fourth is the fatuity of European energy policy. This seems to be getting addressed to various degrees.
