There’s a fairly remarkable interview with Christopher Browning in The Atlantic Online, with a very interesting final paragraph:

“The various perpetrators who became involved in the Final Solution and their decision-making processes were not unique. In fact, I would argue that many of the elements in this were a coming together of quite common factors and ordinary people. That, I think, is very important to recognize if we don’t want to place the Holocaust apart as some kind of suprahistorical, mystical event that we cannot fathom and shouldn’t even try to understand.”
