At the yalta conference what did the Soviets commit to once the war in Europe was over?

At the Yalta Conference in February 1945, the Soviets committed to entering the war against Japan three months after the defeat of Nazi Germany. Additionally, they agreed to participate in the establishment of the United Nations and to allow free elections in Eastern European countries, although this commitment was not fully honored in the subsequent years. The agreements made were aimed at fostering cooperation among the Allied powers but laid the groundwork for future tensions in the Cold War.
