Why did the Versailles system established after World War I fail to maintain world peace, but collapsed rapidly?
As soon as the Versailles system was established, its defects were pointed out.

Archduke Ferdinand of the Austro-Hungarian Empire was assassinated in Sarajevo on June 28, 1914, so the Austro-Hungarian Empire declared war on Serbia on the grounds of the Sarajevo incident, and then Russia responded, you dare to hit my brother in Yugoslavia, I dare to hit you. At this time, Germany jumped out and shouted, "if you touch my good friend Austria-Hungary, I dare to touch you." So after a round of friends from all sides, the world war officially broke out.

the most obvious and major mechanism defect of Versailles lies in the lack of a sufficiently effective coordination mechanism among great powers, especially the lack of great power with sufficient voice to uphold the treaty.

another problem with the Versailles peace treaty is that it is anti-Soviet and anti-communist.
