I don't buy his entire premise but the rise of xenophobia is definitely on the rise:
Xenophobia grows in Germany towards Turks, Arabs and Jews: "From the point of view of Generational Dynamics, unfortunately none of this is a surprise. The survivors of WW II saw how 1930s xenophobia led to wars of extermination, and as long as they were in charge, xenophobic tendencies have been kept to a minimum. That’s why we would have seen very few of these tendencies in the 1990s. What we’re seeing today is truly remarkable — the rapid growth of xenophobia around the world, in many different forms, for the first time since the 1930s. The path to world war is becoming clearer and clearer."
