Shortly after World War II, Mayer, an American journalist and college instructor, went to Germany and befriended a small group of 10 “ordinary Germans” who had lived and worked through the war, and interviewed them in depth.

Mayer’s burning question was, “How does something like Nazi Germany happen?”

What he learned was every bit as shocking as President Obama drawing the same parallels. He wrote, presciently, “Now I see a little better how Nazism overcame Germany - not by attack from without or by subversion from within, but with a whoop and a holler. It was what most Germans wanted – or, under pressure of combined reality and illusion, came to want. They wanted it; they got it; and they liked it.
