Why did Stalin accept Truman's proposal at potsdam?

Stalin accepted Truman's proposal at the Potsdam Conference primarily to secure Soviet interests in Eastern Europe and to maintain the momentum of the post-war order. By agreeing to cooperate with the West, he aimed to strengthen the Soviet position in the face of potential Western unity against communism. Additionally, Stalin sought to gain time to solidify Soviet control over Eastern European countries while assessing the West's intentions. Ultimately, his acceptance was a strategic move to leverage the situation to the USSR's advantage.
