The Treaty of Versailles was subject to multiple criticisms. The frustrations and imbalances that gave birth, had an important role in the decades that followed. Adolf Hitler opposed, since his political ascension began, the Treaty of Versailles, which made all the consequences of the war on the shoulders of Germany, which would then be transformed into hyperinflation. In fact, according to article 231, Germany is considered to be responsible for the war.
The Senate of the United States did not want to sign the treaty and thus prevented the United States from entering the League of Nations, which from the beginning reduced the power of this organization. The effects of the treaty were one of the causes of the Second World War.
The war causes of the outbreak of the Second World War are, in the West, the invasion of Poland by the German troops and, in the East, the Japanese invasion of China, the British, Dutch colonies and later the attack on Pearl Harbor.
The Second World War broke out after these aggressive actions received in response a declaration of war, armed resistance or both, by the countries attacked and those with whom they maintained treaties. At first, the allied countries were formed only by Poland, the United Kingdom and France, while the Axis forces were constituted solely by Germany and Italy in an alliance called the Steel Pact.
As the war progressed, the countries that were entering it (due to being attacked or having treaties with the aggressed countries) were aligned on one of the two sides, depending on each situation. That was the case of the United States and the USSR, attacked respectively by Japan and Germany. Some countries, such as Hungary or Italy, changed their alliances in the final phases of the war.
