It might be a good idea if the various countries of the world would occasionally swap history books, just to see what other people are doing with the same set of facts.

Vaughan’s quip points to how “history” is often less a neutral record than a national story shaped by selection, emphasis, and interpretation. By imagining countries swapping textbooks, he highlights that the same events can be narrated as triumph or tragedy depending on who is telling the tale—and that patriotic framing can quietly turn into bias or propaganda. The line also implies a practical remedy: comparative reading. Encountering another nation’s account can expose omissions, challenge inherited assumptions, and cultivate humility about one’s own narrative. In a single sentence, the joke becomes an argument for historiographical awareness and cross-cultural literacy.
