The correct answer is A) Germany still would have gone into a Great Depression because the rest of the world did, so it would have changed nothing.
The statement that refutes (or disproves) this thesis is "Germany still would have gone into a Great Depression because the rest of the world did, so it would have changed nothing.
The thesis was: ... "The punishment of Germany by the Allies in the Treaty of Versailles was one of the major factors that led to the rise of Hitler and World War II."
Furthermore, Hitler's ambition was unstoppable. Let's remember that British Prime Minister Neville Chamberlain has adopted the policy of appeasement to give Hitler the Rhineland territory in order to avoid another bloody war such as World War 1. But the Germans troops invaded Poland on September 1, 1939, and this represented the beginning of World War II.
The other options of the question were B) Germany would not have wanted revenge if they were given a just peace so there would be no need to fight again. C) The Weimar republic would not have been as weak and would have been able to survive the great depression. D) Nationalism was not present in Germany after World War I.
