The Assyrians fleeing en masse might actually be the best result for them in TTL. With the Armenians probably being by and large in Russian and possibly the British Cilician state we’ve discussed a few times, the Assyrians are going to be one of the main focuses of Ottoman rage in a post war environment. Fleeing to a potential French Lebanon, potential British Cilicia, Or Greece might be their best bets here. Cyprus could be another option even if it’s still in ottoman hands as they could likely find safe haven their among the Greeks. I can see it being a lot like the miracle at Dunkirk actually. Small Greek fishing vessels arriving in various ports or just along the coast in general to ferry people a few at a time to safety as best they can.
