For my generation, clickbait. For the younglings, it’s “Who’s MacArthur”?
Or as the Code puts it, "terrorism" involves crimes that:
Appear to be intended (i) to intimidate or coerce a civilian population; (ii) to influence the policy of a government by intimidation or coercion; or (iii) to affect the conduct of a government by mass destruction, assassination, or kidnapping.
The MacArthur report was not even taken to Yalta. However, it was carefully preserved in the files of the high command and subsequently became the basis of the Truman-Attlee Potsdam declaration calling for surrender of Japan.
That's a real Time Magazine cover, by the way. May 9, 1949. The caption reads "MacArthur of Japan: A decision for the next 1000 years".
