The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
Was the supposed unfairness of the Treaty a significant contributor to the rise of the Nazi party in Germany--or was it merely a convenient rhetorical tool for German politicians to exploit?
I think that the terms of the Treaty of Versailles were unfavorable for Germany, although, this nation had to assume part of its responsibility for the damage and destruction caused during World War I.
Under the Treaty of Versailles, signed in Paris, France, at the end of World War I, the victorious allies forced Germany to pay for the repairments. It was a fortune. Germany also lost some territories.
Yes, the supposed unfairness of the Treaty was a significant contributor to the rise of the Nazi party in Germany. But let's be honest, the Weimer Republic was not successful to rebuild the country that suffered from poverty. The political conditions were set to the arrival of dictator Adolph Hitler and the Nazi Party. He was the kind of leader Germany needed at that time. He found the perfect circumstances in Germany to flourish.
