The purpose of the conference was to discuss post-war settlements[8] and to reach a final agreement concerning “the UN’s structure and membership and set the date of the San Francisco organizing conference.”[9] The world leaders eventually agreed on Roosevelt's proposal to give certain members a veto power[10] so “that the Organization could take no important action without their joint consent.”[11] Though the veto power question created a lot of disagreement among the different signatories,[12] its inclusion in the charter was never a matter of negotiation for Roosevelt and his allies.[13] Finally, during the Yalta conference, Stalin agreed to make the USSR a member of the United Nations.[9]
