My sense is that Putin is on very thin political ice. He is bogged down in Ukraine in a fight that was predicted to last three days. He has spent billions and lost huge numbers of people and material. Sooner or later his oligarchs are going to make a move on him.
If that happens, it is more likely that Putin is replaced by someone far, far worse.
At least Putin was trying to have an agreement with the West, but Obama/Biden were not honest brokers.
