The US had absolutely no bloody right not to include Zalenskyy. You remember him, right? The president of the invaded country, who you seem to want to roll over and cede at least half of his country's mineral wealth to a fucking racketeer. Peace talks MUST involve both parties.
You know it will be illegal in Ukraine for Zelensky to attend peace talks, why did he pass that law if he was interested in negotiations? Zelensky only became interested in negotiations when he realised he was being excluded. He has no interest due to what will come out when he is out of power.
