This thesis by Sir John Glubb is well worth the half hour it will take to read it. It discusses human cultures of recorded history , their rise and fall, the inherent forces which caused them as it relates to the USA today. All that we face today, from Iran to ISIS to southern border illegals is nothing new and in fact is expected. The pattern follows the same curve through out history, regardless of which country or culture is involved. I guarantee anyone who reads this will have a new outlook on the forces arrayed against us and a renewed resolve to defeat them.

“The only thing we learn from history, is that men never learn from history.”

“Another remarkable and unexpected symptom of national decline is the intensi-
fication of internal political hatreds. One would have expected that, when the survival
of the nation became precarious, political factions would drop their rivalry and stand
shoulder-to-shoulder to save their country. In the fourteenth century, the weakening
empire of Byzantium was threatened, and indeed dominated, by the Ottoman Turks.
The situation was so serious that one would have expected every subject of Byzantium to
abandon his personal interests and to stand with his compatriots in a last desperate
attempt to save the country. The reverse occurred. The Byzantines spent the last
fifty years of their history infighting one another in repeated civil wars, until the Ottomans
moved in and administered the coup de grâce. ”
