 The Red Army withheld assistance to Polish resistance fighters battling the Germans in the Warsaw Uprising, with Stalin believing that any victorious Polish militants could interfere with his aspirations to dominate Poland through a future Marxist government.Although concealing his desires from the other Allied leaders, Stalin placed great emphasis on capturing Berlin first, believing that this would enable him to bring more of Europe under long-term Soviet control.Churchill was concerned that this was the case, and unsuccessfully tried to convince the US that the Western Allies should pursue the same goal.
