They could announce the end of the war, but would instantly find themselves embroiled in a new one. NATO will not tolerate the use of nuclear weapons, even tactically. It's the reason that the organization exists. Russia has made nuclear threats at NATO nations and it's only the fact that they've never used a nuclear weapon that keeps Russia from being forcibly disarmed. It's hard to see a route whereby that does not escalate. But there is no chance that NATO will say, "Well, I guess you win Ukraine, congratulations".
