In the Conquest of Paradise (1990), Sale condemned the British and American people for pursuing a genocidal program for more than four centuries (Lewy, 2004).

Measles, influenza, syphilis, bubomic plague, typhus, and cholera were only a few of the other plagues that the "visitors" bequeathed to the inhabitants already living on this soil.
