(1) “Europe” was not a concept in the 14th century. Certainly, the Byzantines, although Christian, don’t fit into this Western-eurocentic thing. But I digress.
(2) It’s a fun historical analogy but it’s inapt. As far as anyone knows, the Crusaders actually wanted to win and by then Crusading was a 300-year-old policy. Now, I believe that Conservative White America wants to “win.” But the difference is, I think the Crusaders’ leaders actually wanted to win. The Kochs, et al. don’t give a shit if CWA wins. Their generalship is why they need a new grand strategy but also why they won’t get one.
