i didnt see putin demanding anything.
he offered conditions that he would like met if military operations are to seize.
So, if I come to your house, beat you over the head with a bat and then lay a set of "conditions" in front of you to get me to stop beating the fuck out of you, what would you call them? I'd call them DEMANDS. Again, anyone demanding anything from anyone else forcefully rather than ASKING in a civilized manor completely deserves to get their face beat in or worse. The point still stands, demands only belong in parenting and absolutely nothing else.
The Russian military personnel are learning this the hard way. If they dont have the brains or courage to desert/surrender, then they deserve to get their face bashed in for trying to demand something of the people they are attacking.
This war only ends 1 way. With the untimely death of Putin which will need to come from someone within his inner circle. Bending to his demands will only lead to MORE demands. It will likely be demands of other countries like Poland, the baltics, and eventually the whole of europe, we've seen this before, history likes to repeat itself when lessons learned fade away.
