White America: The American Racial Problem as Seen in a Worldwide Perspective by Earnest Cox

A masterful survey of the relationship between racial homogeneity and the preservation of civilization, described against a sweeping historical backdrop which includes Egypt, India, South America, South Africa, and finally the U.S.A.

The author proves how racial mixing has in every case led to the collapse of the original founding civilization, and that the only solution to the problem is not segregation, but total physical geographical separation.
