Life was different after the Great War, (Which is how the JW's manage to pedal the alleged significance of 1914 in Europe, which has a much better grasp of their own history than Americans do) but I agree that tensions had been at a boiling point for decades.
Even today, a German historian would likely disagree with this statement:
"While one camp, joining Great Britain, France, and Russia (Triple Entente) strove to preserve the fragile balance between the European great powers, the second camp formed around German Empire, Austria-Hungary, and Italy (Central Powers) was challenging it."
(Especially the part about Italy)
