The irony here is that the author quotes Sun Tzu about the importance of knowing one’s enemy, but never once dares to utter the name of that enemy. Which tends to underline why Americans lost their country and why other European nations are now at risk of losing theirs; as long even the most die-hard right-wing conservatives still give lip service to “judeo-christianity” and “civic nationalism”, there is no chance of ever winning any battle.
