At the Yalta Conference, the Allies agreed that the liberated nations
of Europe would create democratic governments of their own choice,
defeated Germany would be divided into occupation zones, Germany would
pay war reparations, and the Soviet Union would enter the war against
Japan.

to enter the war against Japan after Germany 's defeat and was to
receive important territorial concessions in return. The Big Three also
agreed to establish a postwar world organization. Most controversial was
their understanding to hold free elections in recently liberated Poland
, an agreement that the Soviets failed to abide by and later opened
Roosevelt to charges of being naive. </span>
