2011 World Politics question #13

On p. 250, Todorov writes: "'The man who finds his country sweet is only a raw beginner; the man for whom each country is as his own is already strong; but only the man for whom the whole world is as a foreign country is perfect' (I myself, a Bulgarian living in France, borrow this quotation from Edward Said, a Palestinian living in the United States, who himself found it in Erich Auerbach, a German exiled in Turkey)." Is this in fact the best way to avoid genocide in cross-cultural encounters?
