Kushner and Witkoff spent two hours with Putin in Moscow. Another meeting, nothing else.
Putin still wants Ukrainian territory that Russia hasn't even conquered. There are no European soldiers in Ukraine. The US wants Europe to be involved in the negotiations. Russia opposes. Russia wants a "new Yalta" that will reshape Europe's security order. More talks have been promised, no ceasefire.
10 visits to Russia by Kushner and Witkoff, and all they achieved was a prisoner exchange.
