Identify elements from the Treaty of Versailles that would support the following quotation: "Peace is never long preserved by weight or metal or by an armament race. Peace can be made tranquil and secure only by understanding and agreement fortified by sanctions."
The original question had to be edited. I would suggest that much in the Treaty of Versailles would support the main idea of the quotation. The Allies' imposition of harsh economic reparations on Germany might be one example of how "peace is never long perserved by weight or metal." But the belief that making Germans pay money back to the Allies would ensure a long and sustaining peace was misguided. It only sought to increase resentment and help to add fuel to the rise of Hitler with its economic crippling of Germany. At the same time, the idea of an "armament race" could be seen in the Allied attempt to disembowel Germany's political and military capacity in the name of the treaty. Additionally, the scramble for German colonies enhanced a type of "colony race," similar to one of armaments. In these instances, the Allied powers went against their own ideas expressed in the treaty.
Finally, I would suggest that the last portion of the quotation directly underscores how the Treaty of Versailles was not a lasting treaty. The idea of peace being "tranquil and secure" through "understanding and agreement" negates the presence of secret alliances and secret deals. Yet, this is exactly what President Wilson found at the Versailles peace conference. The Allied Forces having cut deals with one another at the cost of German autonomy is precisely the practice that is not "tranquil" or "secure," denying any hope of agreement.
In the end, the quote goes very far to demonstrating how the Treaty was more of an Armistice that helped to set the stage for World War II.
