@AmeenahHs how many marks do you think this is?
The Grand Alliance was somewhat important for the relations between the big 3 because during the Potsdam it was confirmed that Germany would be split in 4 sections. In 1945 Yalta conference the big three decided that they would split Germany into 4 zones one for each ally. Britain, France, The USSR and The USA received a section. This also split Berlin up into these zones even though it was in east Germany. This caused tension between the USSR and USA because they were disagreed over the splitting of Berlin. Therefore, the Grand Alliance was somewhat important for the relations between Stalin, Churchill and Roosevelt.
The Grand Alliance was slightly important for relations between Stalin, Churchill and Roosevelt because it caused disagreements between Stalin and Roosevelt over the German reparations. In the 1943 Tehran conference there was a disagreement over how harsh the Allies should be on Germany when they won the war. Stalin felt that they should be very harsh on Germany because of the huge impact that the war had had on the USSR, but Churchill and Roosevelt thought they should be more lenient with Germany to allow them to recover post war. This caused tension between the Leaders and worsened relations. Therefore, the Grand Alliance was slightly importance for relations between Stalin, Churchill and Roosevelt.
