The Treaty of Versailles is the Point of Divergence of No to Nazism. Instead of the normal terms that were dictated in the Treaty of Versailles in OTL, the Fourteen Points were enacted, although hesitantly by the French particularly. This came about due to Wilsons health not deteriorating until slightly later, when the treaty was signed by all parties. These terms were a lot lighter on Germany, which lead to the National Socialists never gaining a significant amount of power.
The French were outraged by the light terms of the USA, pointing out that they had the Atlantic to defend them against German aggression, but Wilson, with some help from the British, overruled the French concerns. American-French relations deteriorated following the treaty and also, though to a lesser extent, Anglo-French relations. French-German relations still remained like OTL. American-German relations improved because of the treaty.
Terms of the treaty
I. Open covenants of peace, openly arrived at, after which there shall be no private international understandings of any kind but diplomacy shall proceed always frankly and in the public view.
II. Absolute freedom of navigation upon the seas, outside territorial waters, alike in peace and in war, except as the seas may be closed in whole or in part by international action for the enforcement of international covenants.
III. The removal, so far as possible, of all economic barriers and the establishment of an equality of trade conditions among all the nations consenting to the peace and associating themselves for its maintenance.
IV. Adequate guarantees given and taken that national armaments will be reduced to the lowest point consistent with domestic safety.
V. A free, open-minded, and absolutely impartial adjustment of all colonial claims, based upon a strict observance of the principle that in determining all such questions of sovereignty the interests of the populations concerned must have equal weight with the equitable claims of the government whose title is to be determined.
VI. The evacuation of all Russian territory and such a settlement of all questions affecting Russia as will secure the best and freest cooperation of the other nations of the world in obtaining for her an unhampered and unembarrassed opportunity for the independent determination of her own political development and national policy and assure her of a sincere welcome into the society of free nations under institutions of her own choosing; and, more than a welcome, assistance also of every kind that she may need and may herself desire. The treatment accorded Russia by her sister nations in the months to come will be the acid test of their good will, of their comprehension of her needs as distinguished from their own interests, and of their intelligent and unselfish sympathy.
VII. Belgium, the whole world will agree, must be evacuated and restored, without any attempt to limit the sovereignty which she enjoys in common with all other free nations. No other single act will serve as this will serve to restore confidence among the nations in the laws which they have themselves set and determined for the government of their relations with one another. Without this healing act the whole structure and validity of international law is forever impaired.
VIII. All French territory should be freed and the invaded portions restored, and the wrong done to France by Prussia in 1871 in the matter of Alsace-Lorraine, which has unsettled the peace of the world for nearly fifty years, should be righted, in order that peace may once more be made secure in the interest of all.
IX. A readjustment of the frontiers of Italy should be effected along clearly recognizable lines of nationality.
X. The people of Austria-Hungary, whose place among the nations we wish to see safeguarded and assured, should be accorded the freest opportunity to autonomous development.
XI. Romania, Serbia, and Montenegro should be evacuated; occupied territories restored; Serbia accorded free and secure access to the sea; and the relations of the several Balkan states to one another determined by friendly counsel along historically established lines of allegiance and nationality; and international guarantees of the political and economic independence and territorial integrity of the several Balkan states should be entered into.
XII. The Turkish portion of the present Ottoman Empire should be assured a secure sovereignty, but the other nationalities which are now under Turkish rule should be assured an undoubted security of life and an absolutely unmolested opportunity of autonomous development, and the Dardanelles should be permanently opened as a free passage to the ships and commerce of all nations under international guarantees.
XIII. An independent Polish state should be erected which should include the territories inhabited by indisputably Polish populations, which should be assured a free and secure access to the sea, and whose political and economic independence and territorial integrity should be guaranteed by international covenant. XIV. A general association of nations must be formed under specific covenants for the purpose of affording mutual guarantees of political independence and territorial integrity to great and small states alike.
The Germans supported the treaty and were far more eager to accept it than the Treaty of Versailles in OTL. The Americans also supported the treaty as they were the ones to create it. Both of these nations were fine with the terms. The Americans were supported to some extent by the UK. The Italians were also happy that the terms on Germany were not too harsh.
The French however, were outraged with the treaty, claiming that the Germans were being let off the hook by the light terms of the Fourteen Points. They demanded harsher terms, which the Americans refused outright. The French refused to sing, the treaty, which resulted in a continuation of World War One called the Franco-German War(Not to be confused with the Franco-Prussian War). The Japanese were OK with the treaty, although they would have liked more land.
