Political decisions : Stalin and Churchill discussed the future borders of Poland and settled on the Curzon line in the east and the Oder-Neisse line in the west . FDR had asked to be excused from any discussion of Poland out of consideration for the effects of any decision on Polish voters in the USA and the upcoming 1944 election . This decision was not ratified until the Potsdam Conference of 1945
