abstract:The Molotov Plan was the system created by the Soviet Union in 1947 in order to provide aid to rebuild the countries in Eastern Europe that were politically and economically aligned to the Soviet Union. It can be seen to be the USSR's version of the Marshall Plan, which for political reasons the Eastern European countries would not be able to join without leaving the Soviet sphere of influence.
Hitler's plan to attack Poland predates the Molotov-Ribbentrop pact, so that deal, shameful though it was, did not provide the definitive go-ahead for the invasion.
