Watching Nuremberg last evening reminded me of this: "A Political Warning from the Past"

Decades after a U.S. Army psychiatrist who studied the Nazis predicted a threat to American democracy, we should remember his fears when we vote.

Psychiatrist and U.S. Army Lt. Col. Douglas M. Kelley returned home in 1946 after spending six months studying the most loathsome of the captured German leaders after World War II. I tell his full story in my book The Nazi and the Psychiatrist.

He was afraid. Kelley, who had served among the prisoners as a staff physician at the Nuremberg jail before and during the celebrated international tribunal that charged 22 top Nazis with war crimes and crimes against humanity, didn’t fear for the fate of Germany or Europe. He agonized over the future of America.
