There is just like 40 years difference. Aristocratic boys 20 years old in 1890 were men running things in 1914 (start of WWI). Kids born in 1890 were 40 years old in 1930 - the generation that started WWII.

Prussian militaristic culture had to do and influenced with both events.

1960 events like communist scare, cold war, civil rights fights and lynching are absolutely relevant to contemporary American culture and politics.
