Message of self-determination-- for the Allies the goal of the war was to restore democracy and all countries to determine their own government.
Due to the idea of self-determination, many colonies in Asia believed that in fighting for the Allies they would be granted independence. Colonies such as India, Vietnam, and China sent representatives to the treaty negotiations in hopes they would be repaid for their services. Instead, colonies were maintained or even shifted hands. Colonial leaders were rejected from meetings and created a sense of anger that translated to independence movements.
