One of Donald Trump's most revealing quotes was to say, "Who knew health care was so complicated?" He has now made a similar acknowledgement about North Korea, stating that a 10-minute conversation with the Chinese leader has illuminated him upon that subject as well. What these comments really indicate, of course, was how poorly prepared he was to accept the mantle of the presidency in the first place. His naivete and arrogance were evident in thinking that making public policy was the same as negotiating New York City real estate deals. Finally he is beginning to recognize that he didn't know what he didn't know.
