I saw Major Johnstone, the Harvard Professor who is here to lay the bases of an American History. We discussed the right name of the war. I said that we called it now The War, but that this could not last. The Napoleonic War was The Great War. To call it The German War was too much flattery for the Boche. I suggested The World War as a shade better title, and finally we mutually agreed to call it The First World War in order to prevent the millennium folk from forgetting that the history of the world was the history of war.
-- Charles à Court Repington, September 10, 1918 (with emphasis added)
Historical revisionism happens when someone ignores history because they want to win an argument. Which is what you just did. Which is particularly ridiculous given you were just using that as an analogy to make some other point. But the fact is, that while most people called it "The Great War" while it was ongoing, historians started calling it the "First World War" before the war had ended.
