Versailles Conference and Washington Conference! These two meetings mainly discussed redefining world hegemony and sphere of influence! It constitutes the Versailles-Washington system! There are complex contradictions in the system of "Versailles Peace Treaty is only a 20-year truce". The victorious country believed in "might is right" and put the defeated country in a position of being trampled and enslaved by unequal treaties, thus deepening the contradiction between the two; Due to the uneven distribution of spoils, the contradiction between the victorious countries has not really subsided; Imperialism's "mandated rule" over the defeated colonies further deepened the contradiction between imperialism and colonies. Therefore, Lenin said that "the international relations maintained by the Versailles system are based on volcanoes." Can't last. The defeated country is in a position of being slaughtered and enslaved, and hatred is growing gradually. This is because German Nazism rose by hating the victorious country. Set the stage for the outbreak of World War II.
