Partially. The Krim will stay russian territory and the Dombass probably also. The Ukaine must stay a neutral territory to keep the peace. And the attacks on the people of these territories from the Ukraine must also stop. Then I think its possible to retain the peace in Europe. But with the USA as our "allies" and Biden as President I highly doubt its possible. The USA makes a ton of money with this war.
On the other hand, when Russia sees they can get away with seizing territories just like this they might try it again and again.
