Most of the talk about him is pithy quotes and his leadership during the war. Not things he actually did, just that he was the leader at the time. Even his own military service is separated from his leadership, unlike most other "wartime leaders" we admire, with him just being known as a fat drunkard most of the time.
They could teach things to admire about him (other than being a slightly clever asshole), but instead they just say he existed and that's great. Which is why people might call him the greatest, but have no idea why they think that.
