Although the Versailles-Washishton system was based on the advanced achievements of international law (the desire to abandon war, the solution of all issues through multilateral negotiations, etc.), in fact, from the beginning it resembled a kind of “get-together” when the countries – eaters “ripped off” other territories in their favor and appointed moral compensation for damage caused during the war. Many countries then remained dissatisfied with such a “carve-up”, including some countries – the winners And Germany was “put on the counter” at all. Therefore, the Versailles-Washington system, in principle, was a “time bomb”. Any country could rebel at any moment and not maintain the conditions of this system.

Then it became clear that the states that had achieved the signing of the pact were not ready to defend it. That is why the guarantor countries did not “rush” to defend China and Abyssinia.
