What were the contradictions of the Versailles system of the world?

In 1918, the bloodiest war at that time – the First World War – ended. The winning countries made a decision about the “future of the world.” This was decided at the Versailles Conference in 1919. The countries needed not only to decide the fate of the vanquished, but also to establish a new world order. The result is twofold. On the one hand, for the first time, peaceful mechanisms for resolving conflicts were created at the level of all countries – the creation of a League of Nations body. The system of international law began to form. On the other hand, this peace treaty doomed the world to World War II. 1) The size of the indemnity doomed the young German Republic of Versailles to death, the economy simply could not cope. In the end, the ideologues of revanchism would have come to power in any case; 2) New states (for example, Czechoslovakia) were created on the ruins of former empires without taking into account national issues, therefore, peoples often in ethnic conflict fell into one state; 3) The interests of the young Soviet Russia were not taken into account; 4) As a result, England, France and the USA received the main advantages, small states were left on the sidelines; 5) And the organ of the League of Nations itself was of little use, because the means – economic sanctions rarely acted on the aggressors.
