For context, Russia invaded Ukraine and grabbed a bunch of Ukrainian territory, knowing that Ukraine has 4x smaller population and no oil money to fund military production. It took months for Ukraine to coordinate things with the West and to start slowly retaking it back. Now Russia is offering "peace talks", i.e. asking to keep the land they already grabbed, now that the tide has turned.

It makes full sense that Ukraine wouldn't agree to it. If they really wanted peace, they could offer to withdraw their troops from the territories grabbed after 2014. Ukraine would be more than happy to accept that.

It's like you got robbed in a dark alley, spent some time tracking down your stolen phone, brought the robber to the police station, and now he's offering sincere apologies if you let him keep the phone. And you are somehow that bad person for not accepting them.
