I understand your distress regarding Germany's history, but if we really want to understand the genesis of everything that happened, we also need to look at the role the United States played. Without the intervention of the USA, Germany would never have been able to recover after World War I. The Dawes Plan, which restructured Germany's debts and provided loans, actually gave new life to a destroyed economy, and contributed to the stabilization period that created fertile ground for the rise of extremist ideologies like Nazism.
Had France been listened to, and Germany had been truly disbanded and reduced to a state of permanent misery, it would not have been able to recover and set the stage for the rise of Nazism. But the United States, through their economic policies, made a recovery possible that allowed a failed painter and his dangerous ideas to gain traction.
Moreover, we cannot ignore the influence of racist ideologies, such as those promoted by the Ku Klux Klan in the United States, which had an impact on similar movements in Europe. Ideas of racial supremacy and hatred toward minorities unfortunately spread globally. The United States not only helped revive Germany, but with their example of racism and intolerance, they also fueled the hatred that would later turn into Nazism.
There's another important aspect to consider: with this intervention, the United States not only facilitated Germany's recovery but also marked the end of European global dominance, which had lasted for centuries. France and Great Britain, despite winning the war, were now weakened and incapable of fully recovering from the devastating costs of the conflict. This opened the door for the United States to emerge as a new global economic power, while the Soviet Union, with its communist ideology, was rising as an alternative superpower.
Thus, the United States not only made Germany's economic recovery possible but also accelerated the decline of European hegemony, shifting the global center of power first toward them and then toward Russia. This shift had enormous effects on geopolitical balances, leading to a new global division that would define the Cold War and reshape the world order for the rest of the century.
In short, without the intervention of the United States, Germany would likely have been doomed to permanent misery, and without its economic recovery, it is hard to imagine how a regime like Nazism could have gained so much power. Therefore, the USA not only fueled the growth of an extremist movement but also contributed to the decline of European hegemony, accelerating the emergence of a new world order that saw the rise of the two superpowers of the 20th century.
However, this does not diminish the grave responsibility in the human slaughter of millions of people that occurred during that period. I have visited all the concentration and extermination camps, and I can say with certainty that they are truly the symbol of human madness.
