African, Asian, and Latam exchanges included, many of which go defunct. Japan’s has been basically flat among developed countries
Worth noting that a stock exchange becoming defunct is not the same as the value of the index associated with the stocks listed on that exchange going to zero.
For example numerous US stock exchanges also go defunct. Nevertheless the value of the stocks that traded on those exchanges remains unaffected. It's not like if NASDAQ went out of business tomorrow that Google and Microsoft would all declare bankruptcy.
