It is as if all the sanctions giving to Russia is not trobling them and they seems to be adamant , stick to their decision by invading Ukraine. I think putin is not ready to end the war anytime soon.
You are absolutely right that Putin is not going to end this war until he achieves all his objectives including regime change because President Volodymyr Zelensky is not ready to give up his desire to join Western Alliance of NATO. However I think he has successfully reduced Ukraine ability to combat Russian forces after huge bombing attacks on its military installations. Continuation of this war is a big threat to world peace so world leaders must find a negotiated settlement at the soonest.
