Sorry to take up space, but purportedly to be from "Merrill's Marauders: The truth about an incredible adventure" in the January 1957 issue of Harper's Magazine: "We trained hard, but it seemed that every time we were beginning to form up into teams we would be reorganized. Presumably the plans for our employment were being changed. I was to learn later in life that, perhaps because we are so good at organizing, we tend as a nation to meet any new situation by reorganizing; and a wonderful method it can be for creating the illusion of progress while producing confusion, inefficiency and demoralization."

A great quote regardless of who said it. Don't know about the 1970 attribution as I had it posted in my offices while on active duty beginning in the early 60s.
