NPR described Reston as an historian, so I looked that up. He has written 11 books, but apparently "popular history" is a generous description. Polemic is another. He probably lives off of his father's fame as a NYT columnist. Here is one estimate of his worth, according to Amazon "Get James Reston, Jr.'s Amazon Short, Behind the Damask Curtain, for just 49¢."
There is a time to polemicize and there is a time to refrain and this is one of those times.
