Question1
At the end of World War 1, an agreement was made, and the Treaty of Versailles was signed. This particular treaty placed blame on Germany for being responsible for the war thus it exerted significant punishments on the Germans that ended up harming the people and the country as a whole. The Germans protested almost immediately on the potential damage that the issues outlined in the treaty were causing. There were complaints which included; the fact that the treaty had the power to make Germany a debtor slave to all the others powers of Europe.
Germany was also going to be treated like a bankrupt nation by the victorious countries such as France and England and was to pay reparation or penalties in amounts which were capricious and arbitrary in nature. Germans economic development was to be hampered by outside powers through the control of construction of infrastructure and Germans rivers. All of Germans property abroad was going to be annexed and not allowed to conduct trade with the rest of the civilised world.
Question 2
Wilson's vision for peace was thwarted when the economic difficulty that German was to endure was outlined under the treaty. Some of the points that contradicted Wilsons expectations included; the fact that he did not place blame on any country for being responsible for starting the war, but rather those alliances and institutions that existed before, yet the treaty chose to blame Germany. Wilsons believed that peace would prevail if all countries in Europe were treated equally and allowed to participate in any economic developments; however the treaty denied German this participation and equality. He also had a vision that the League of Nations will meet and settle their differences amicably; however, Germany was not allowed to attend any of those assemblies. His vision of self-determination apparently did not apply to Germans.
Question 3
In the document, an appeal is made which asserts that the fundamental law of rights should be implemented. This is because individuals' posses' innate rights that should be respected and thus the fundamental rights should be applied in all states. Some of these rights include self-determination and the rights of self-preservation.
Question 4
Yes, I agree Germany wasn't getting fair treatment. All the European countries were devastated by what took place during world war 1.their infrastructures, properties and economies were severely damaged, millions of people died, and debt was acquired. The victors, due to their personal interest decided to recoup from Germany some of the damage. They decided to put Germany in shackles while they tried to recover. They had a short sighted vision thus failed to consider the possible long-term consequences of their actions. President Wilson Woodrow came up with a plan for peace in Europe that would have brought about different outcomes. However, his ideas were ignored by the European powers and instead they chose to revenge. Since they had their interests, they decided to disarm Germans and thus took over their territory.
Germans became vulnerable and were ruled by foreign powers while France and Britain were given a chance to recover from the war. The treaty made it almost impossible for Germany to heal economically or politically. The psychological impact created by the agreement was significant to the Germans. They were made to feel inferior and ashamed of the rest of the European powers due to the guilt clause. All these factors combined led to the social and political unrest in Germany that brought about the creation and establishment of a fascist regime during the 1930s.
