Christianity and nationalism are incompatible.  Why would an all-seeing, all-loving god pick Americans to favor above all others.  And yet huge numbers of Americans regard their country as God’s most favoured nation. “It is not easy to see how the more extreme forms of nationalism can long survive when men have seen the Earth in its true perspective as a single small globe against the stars” (Arthur C. Clarke). And yet survive it does, and it has caused the deaths of millions.
