Most of Europe believed might makes right until post WW2. Hell, Spain was still a dictatorship until 1975 and a large part of Eastern Europe was still de facto enslaved until the fall of the USSR. Even now you've got a looming dictatorship in Hungary, a dictatorship in Belarus, a dictatorship in Russia, and a dictatorship in Turkey (a quasi European state). Germany's evil ideology of conquest and might makes right, which was rife in their culture throughout the 18th, 19th and part of the 20th century, was definitely not limited to the first half of the 20th century (not that you were necessarily claiming such). The Nazi ideology was entirely ripped off from existing cultural beliefs that were common in Germany and the greater region at that time and had been for centuries. Hitler was about as non-original as you could get, he simply took common ideas from the culture and swirled them together. Bismarck and Hindenberg were also monsters, Hitler was just worse and was the natural end of their failed, vile culture during those centuries. It took thousands of years for the Europeans to figure out they needed to banish might makes right.
