“If Ukraine doesn’t want to lose more land, they’ll have to compromise on new borders, since they proved unable to protect millions who live in the now-liberated areas. Otherwise, more land will have to be liberated.”
Do you see what you just said? No, you are so blinded by your support of Russia you are not even aware you have blown its cover!
You just confirmed that Russia’s invasion is not about “liberating” ethnic Russians in Donbas and vicinity, but is all about conquest and gaining land. Russia already controls the area it said it wanted to “liberate.” Now you let the cat out of the bag and admitted unless it gets its way, Russia will continue its war of conquest and will move even further into Ukraine, to “liberate” people who don’t want to be “liberated.”
Your Russian handlers are not pleased with you letting the cat out of the bag.
The extra land is obviously necessary to help bring Ukraine to the negotiating table. Eventually they will will understand that.
