The allies had helped them by providing aid in the form of supplies, weapons, military leaders, and soldiers. The allies had a common enemy as well since Spain and France lost the Seven Years War against Britain. Britain had become the major power in Europe and the rest of the world. Spain and France wanted to get revenge and as well regain prestige. The allies had also wanted to regain the lost territory that Britain had taken when they lost the Seven Years War. The allies wanted to gain a new trade partner, the United States. Some people from Europe related to the American fight for independence. They wanted to help free then from Britain's rule. Hope this helps :)
The Potsdam Agreement was the August 1945 agreement between three of the Allies of World Wars 2, the United Kingdom, the United States, and the Soviet Union.

The Idea that the British or the French would come and help them win, is one of the many ideas that gave them hope.
