The closing exercise turns hindsight into a disciplined historical problem rather than an unlimited redesign. The viewer must select a year in the 1920s or 1930s, choose a nation and a decision-maker, and remain there for only one week. Only two books may be carried back, forcing a choice between technical data, strategic warning, and persuasive evidence. The point is to identify one naval weakness that a real contemporary actor could plausibly begin correcting with sharply limited knowledge and time.
