Did Roosevelt and Churchill agree with Stalin in giving him control of Poland?

Roosevelt and Churchill were hesitant about granting Stalin control over Poland, but they ultimately agreed to it as part of the broader negotiations for post-war Europe at the Yalta Conference in February 1945. They believed that appeasing Stalin might help secure his support in the ongoing war against Germany and in establishing a stable post-war order. However, both leaders expressed concerns about Stalin's intentions and the implications for Eastern Europe. This decision was contentious and led to significant tensions in post-war relations.
