Well it was said that Prussia was an Army with a nation vs. everywhere else. (nation with an Army) This militaristic attitude most likely fed the mindset of crushing of the Revolts of 1848 in Germany, and probably had a big influence on starting WW1. A large group of Germans who became disillusioned with the path that Germany was headed down migrated to the US after that. This probably furthered Prussia/Germany down the more aggressive militaristic path.
