Nobody unless they study history understand the context was from 1500 onwards until the Battle of Waterloo in 1815
Where long and drawn out affairs it's was the 23 years of War in Europe which was called the great war by people from the 19th century
From 1793 to 1815
And on the 18th century there was the fight over the balance of power of Europe with the States fighting for who will rule the Europe
Is very similar to the millennium long conflict over who will rule China before unification in 221 BC
I would say it's very much Germany's fault and particularly the Kaiser Otto Von Bismarck after 1871 wanted to avoid War
For Germany as an expanding power and due to being in central Europe any expansion would lead to making everybody nervous
