Hitler's totalitarian leadership as Fuhrer during 1934 until his eventual suicide in 1945 resulted in the persecution of an estimated six million Jews in the Holocaust, and his invasion of Poland in 1939 led to the start of the Second World War.
Actually Hitler's totalitarian leadership as Fuhrer resulted in the murder of an estimated six million Jews in the Holocaust. But why get technical about accurate terminology, eh? Unbelievable.
Meanwhile, in case you're wondering about Smith's comments, Eugene Volokh says "give him a break":
It seems that "Will believes everyone is basically good" is just the reporter's characterization of Smith's statement. Nothing in the quoted material suggests that Smith was saying that Hitler was a good person. Rather, the quoted material simply reports Smith's quite plausible view that Hitler, like many other people who do evil (Smith must have used Hitler as a referent precisely because Smith acknowledges that Hitler did do evil), believe that they are doing good.
A reporter -- mischaracterizing what a [famous] person says? How can that be? At any rate, Smith must've sensed what was coming and made the following statement:
"It is an awful and disgusting lie. It speaks to the dangerous power of an ignorant person with a pen. I am incensed and infuriated to have to respond to such ludicrous misinterpretation. Adolph Hitler was a vile, heinous, vicious killer responsible for one of the greatest acts of evil committed on this planet."
