Interesting chapter, I wonder how long that Ottoman/Anglo alliance will last as while their naturally worried about the Russians their still plenty of Arab nationalists supporters/lobbyists as well as Zionists in Britain. I suspect Britain in WW2 might have some tea for a bit before coming to the Ottoman aid, it would be a tragedy for one of their biggest rivals in the Middle East to need to borrow from them for help in rebuilding their devastated regions.
Well looks Egypt will be going up in flames soon, in hindsight maybe letting settle in Syria would of been better as it means some light artillery and mines could shut down one of the worlds biggest trade ways and likely to get many powers involved and or spike tensions across the world.
The Rakhine question will be a hard one to answer really
It depends on many things but I suspect life might be far worse for Muslim minorities and Chinese across the world in this timeline.
Muslims because of a perceived fifth column, cause for intervention by the Ottomans and and a good way to rally the people, TBH I'm not really sure it would much in Spain, the Philippines or Balkans but Asia has the potnetial of a blood bath like in Cambodia with the Chams, Vietnam, Thailand, India ect.
The Chinese face the same position except worse in places like Burma with a lot of border regions filled with Chinese minorities and once part of the Qing, Vietnam the same and concerns in Laos, Cambodia, Indonesia ect I suspect you see a lot of situations like Malaysia where discrimination causes Chinese to support their own insurgencies.
These prejudices and fears would be made even greater with a open and no quirks Chinese empire with no one child policy, with Formosa adding to their coastline and very close to Japan.
I would not be shocked if a fifth of the world population lives in China in this timeline as time goes with no one child policy and China, by the results of the global market ends up enveloping a lot of it's neighbors in it's economic sphere and made their local industries lowly developed the sure amount of both quality and quality.
I don't mean it as China is going to be the real winner of this timeline more I'm expecting a far darker period for Chinese people outside of well China and potentially a lot ethnic cleansing as a result of this fear.
