That happens in a world where the Ottoman Empire does not collapse in 1918 and modern Armenia doesn't get split from Turkey by the iron curtain. In a world where Armenia remains part of the Empire and the collapse of European power ends the "Armenian question" for a while, population growth that went into the two million Armenians living in modern Russia would have instead fed into the Ottoman Empire. 

It's hard to tell, it could go several ways. But the nice thing about "Go several ways" is that you still have options.
