While I agree with the sentiments about Northern Africa and the Sahel countries as most likely, India is my “dark horse” choice. Yes, BJP and fascism is a big problem. But I think along other metrics, it appears that the conditions seem to be matching up. Recently there were those farmer protests that seemed to have a heavy communist influence that were like the largest protests in human history (I recall something like 200 million people participated in the protest). There’s quite a ways to go but I would not be surprised to see India go communist in this century.
