4) why did both Italy and Japan feel resentment toward the terms of the Versailles Treaty and the outcome of WW1 ? EXPLAIN ASAP​

The Allies and Germany signed the Treaty of Versailles on June 28, 1919. Under its harsh terms, Germany had to accept full responsibility for the conflict. It had to pay the Allies billions of dollars. It had to disarm completely and give up its overseas colonies and some territory in Europe.

The treaty also carved up the Austro-Hungarian and Russian Empires. It created some new nations and restored old ones. Border disputes, however, would lead to future conflicts.

Wilson was able to get his League of Nations included in the treaty. He believed that the League would correct any mistakes in the rest of the treaty. In the months after Wilson's stroke, opposition to the treaty grew. In March 1920, the Senate voted on the treaty with Lodge's changes. It rejected the Treaty of Versailles.

Wilson hoped the 1920 election would be a "great and solemn referendum" on the League. He even considered running for a third term. In the end, however, Wilson did not run. In 1921 the United States signed a separate peace treaty with each of the Central Powers. The United States never joined the League of Nations.
