The beginning of the formation of an anti-fascist coalition?

The anti-Hitler coalition began to take shape in the first month of the Great Patriotic War. On July 12, 1941, a cooperation agreement was signed between the USSR, the USA and England. It provided for help and support in the fight against Germany. On August 16 of the same year, an agreement was signed with the allies of the USSR on the supply of ammunition and food. On January 1, 1942, the Declaration of the United Nations was signed. This document was supported by 20 countries.
The countries of the anti-Hitler coalition were among the winners of the war. The USSR made a great contribution to this victory, since it was the army of this country that laid siege to Berlin, thereby forcing Germany and its allies to surrender.
