As I write a time travel/do-over story that focuses on the Cuban Missile Crisis, with my rule of doing my best to disclose much on the future, I'm tempted to make some comments on what really happened.
For example, I am drawing from a real example, in which the Air Force and Navy thought it would be fairly easy to take down a Soviet surface-to-air missile site. Remember, this is 1962, but the assumption was never tested in combat. We went into Vietnam with the same wrong assumption, and, arguably, it only materialized in 1972.
Would it break the story too much to have a {notice} or some other "editorial note" to speak of lessons that should have been learned?
