In August 1941, Prime Minister Churchill and President Roosevelt met on a ship off Newfoundland and agreed on a plan for large-scale assistance to the USSR.
They also drafted the Atlantic Charter which stated the ideal goals of the war:
no territorial aggrandizement
no territorial changes made against the wishes of the people
restoration of self-government to those deprived of it
free access to raw materials
reduction of trade restrictions
global cooperation to secure better economic and social conditions for all
freedom from fear and want
freedom of the seas
abandonment of the use of force, as well as disarmament of aggressor nations.
