As we've seen since 2014, Russian "peace" overtures are "give us everything and you get nothing". They've also repeatedly proven that they won't honor agreements. They unilaterally broke the Minsk accords just last year with their invasion of Ukraine.
There's no utility in "peace" talks with a dishonest party. All it does is provide the dishonest party with ammunition for propaganda. When the other side balls at their ridiculous demands they run to the press with "look how unreasonable the other side is being!"
