But does the Late 19th Century USA have the will to commit ethnic cleansing against White people (especially White Protestants)? All the areas the U.S. conquered during the Late 19th Century (American West, Puerto Rico, Philippines, Hawaii, Cuba to some extent) were nonwhite, at least by Anglo-American standards, and all of them were also non-Protestant. On the contrary, there is no way that anyone at any point in time could argue that Icelanders are not white, and Iceland was very Lutheran at the time.
