The Germans were made to rebuild their country themselves. They did so. They were told tht they were complicit. The USA at the moment does not have a majority that would accept any responsibility for our collapse.
I work for a German company and I can tell you that The German people and the government are trying really hard recreate the conditions that led to the collapse of Weimar.
I think one of the main reasons that most of Europe is able to engage in social engineering experiments to the extent they have is all the of subsidies they get from the U.S. You can add Israel into that equation as well. Just pulling our military assistance alone would be enough to send most of Europe into a tailspin.
