The treaty of Versailles (28 June 1919), which set the demands on Germany, didn't establish that Germany had to share the responsibility of World War I, it was all the opposite, it set the defeated nation as the aggressor of the war and made it the only responsible for it and consequently it made it pay for the losses and damages caused by the war.
They also had to cede the territories they had obtained during the war, which reduced Germany's population and territory by about 10 percent, and they were demanded a series of measures that dismantled nearly the entire military. such as the restriction of its army to 100,000 men, the elimination of the general staff, the manufacture of armored cars, tanks, submarines, airplanes, and poison gas was, etc.
