Look at what Aleksandr Solzhenitsyn wrote about the “leveling of nations”:
In recent times it has been fashionable to talk of the leveling of nations, of the disappearance of different races in the melting-pot of contemporary civilization. I do not agree with this opinion, but its discussion remains another question. Here it is merely fitting to say that the disappearance of nations would have impoverished us no less than if all men had become alike, with one personality and one face. Nations are the wealth of mankind, its collective personalities; the very least of them wears its own special colors and bears within itself a special facet of divine intention.
