As an aside, I like how the intention of the original poster aged like milk. No one sees “The Great War” as great by those who survived it and by the future. It is not talked about positively in the same way as Napoleonic wars or the Second World War (except if you were an Axis soldier or civilian victim of war crimes of course).
Not trying to glorify wars, but what I’m saying is that some wars have a purpose or cause at least. Like the Napoleonic wars is about new type of government under new found liberal values versus the old system of absolute monarchy that values stability and familiarity. The current war in Ukraine is about stopping imperialism and the wanton violation of international rule (there isn’t technically any rule because international laws are non-binding but that is a different topic I won’t delve for now).
