Article 231 of the Treaty of Versailles Germans viewed this clause as a national humiliation, forcing Germany to accept full responsibility for causing the war. German politicians were vocal in their opposition to the article in an attempt to generate international sympathy, while German historians worked to undermine the article with the objective of subverting the entire treaty. The Allied leaders were surprised at the German reaction; they saw the article only as a necessary legal basis to extract compensation from Germany. The article, with the signatory's name changed, was also included in the treaties signed by Germany's allies who did not view the clause with the same disdain as the Germans did. American diplomat John Foster Dulles—one of the two authors of the article—later regretted the wording used, believing it further aggravated the German people.
Paris Peace Conference, 1919 As the conference's decisions were enacted unilaterally, and largely on the whims of the Big Four, for its duration Paris was effectively the center of a world government, which deliberated over and implemented the sweeping changes to the political geography of Europe. Most famously, the Treaty of Versailles itself weakened Germany's military and placed full blame for the war and costly reparations on Germany's shoulders – the humiliation and resentment in Germany is sometimes considered[by whom?] one of the causes of Nazi electoral successes and indirectly a cause of World War II. The League of Nations proved controversial in the United States as critics said it subverted the powers of Congress to declare war; the U.S. Senate did not ratify any of the peace treaties and the U.S. never joined the League – instead, the Harding administration of 1921-1923 concluded new treaties with Germany, Austria, and Hungary. Republican Germany was not invited to attend the conference at Versailles. Representatives of White Russia (but not Communist Russia) were present. Numerous other nations did send delegations in order to appeal for various unsuccessful additions to the treaties; parties lobbied for causes ranging from independence for the countries of the South Caucasus to Japan's unsuccessful demand for racial equality amongst the other Great Powers.
