It's news because of the context of the negotiations that are currently happening. There is no delusional gotcha here. Russia is defeating NATO in Ukraine. As a result, the US, the main sponsor of NATO, wants to cut its losses. That's why negotiations are happening in the first place. Russia reiterating the root causes for the conflict shows they're not going to make concessions. Now the ball is in American court, they either have to keep allocating resources towards the proxy war, or accept Russian terms. Let me know if any of this was unclear for you.
