Final answer:
Countries such as Italy, France, Japan, and China were discontented with the Treaty of Versailles, which resulted in historical resentment and the May Fourth Movement in China. In the US, opposition ranged from concerns about harsh treatment of Germany to issues of national self-determination.
Step-by-step explanation:
Nations besides Germany were dissatisfied with the Treaty of Versailles and how they were treated, which had lasting historical consequences. Italy felt betrayed because it did not receive the land in Dalmatia it was promised, leading to disillusionment and anti-American sentiment. France was displeased having been granted just part of Germany's African colonies of Cameroon and Togo, while most territories went to Britain. Japan resented the denial of the racial equality clause and was not satisfied with the colonies it received. In addition, the creation of new states like Czechoslovakia did not fully resolve internal ethnic conflicts, setting the stage for future tensions.
China felt ignored when Japan retained control over Shandong, sparking the May Fourth Movement. In the United States, many opposed the treaty on various grounds - some for its harshness on Germany, others for not addressing self-determination or Irish independence sufficiently, contributing to domestic discontent.
The manner in which the Treaty's negotiations were conducted, particularly in regard to the punishment and retribution versus the sovereignty and self-determination of nations, laid the groundwork for the conflicts that would erupt throughout the 20th century, most notably World War II.
