Even if there was peace, apart from money, why are the NRL interested to go to the middle east? Do they have a strategy in regards to that region? If there isn't a strategy, then the middle east could provide a short term sugar hit. Once novelty wears off, what happens then?
I can understand why they want to take a game to London, so they could help out the ESL, a comp which the NRL may invest in. Vegas was initially about gambling, but the NRL is slowly getting itself known with American sports and streaming or media companies.
IMO, the point of having a potential global round is to get the code known, with the right strategies behind it. The money side of it will take care of itself.
