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).
