It caused the rise of totalitarianism that played a major role on causing WWII, as Germany recieved harsh punishment after WWI in the Paris peace settlememt, this left Germany weak and the civilians were outraged and resentful towards their government. Not only were the German violated,the leftover issues such as destruction of infrastructure,the collapse of economy,unemployment,hyper inflation worsened the situation. Desiring for a stronger government,Hitler who lead totalitarianism party rose to power,expansionist policy was adopted and threatened the world peace,which then finally cause Britain to declare war and started WWII
hope it helps :)
