They don't want war, yet they also don't want to make any concessions or de-escalations. So they get more war.

Not sure you can blame them can you? If they concede territory that's just a message of "invade later for more". It's also pretty hard to give concessions when the rhetoric of your opponent doesn't make any sense. Effectively Russia doesn't want Ukraine to be Ukraine one way or another.

> The position of the countries that want "peace" is bizarre in the media: "you should just stop fighting the invader and then it's no longer war. You don't want war do you?"

It’s not “bizarre” just calculated. Most of the world doesn’t give a shit about Ukraine and would be perfectly happy for Russia to annex it so long as the economic disruption from the sanctions and oil price increases stop. They can’t outright say it because western countries are big trade partners but that’s what they mean reading between the lines.
