“WWI was the truly “unnecessary war”.”
WW1 was setup by the Franco Prussian War, which was a result of the Napoleonic Wars, which was a result of the Wars of Empire between Spain, Britain and France, which grew out of the 30 year and 100 year wars in the Middle ages. This doesn’t even count the Ottoman invasions and driving the barbarian Muslims out of Spain.
The issue was that other than the Napoleonic Wars there was always a settlement rather than a winner. The era from 1945 to present is the longest time that I can think of that Europe hasn’t been at war. Maybe since the Roman Empire.
