World War II

World War II functions in the novel as a cultural reference point, not as a directly depicted conflict. Its presence is carried by talk about history and by the period atmosphere of a USO dance, linking the past to present-day courtship, family interaction, and Lara Jean’s shifting sense of time.

Historical Reference and Period Nostalgia

At a gathering with Lara Jean’s father and Ms. Rothschild, the conversation turns to the 1940s. Ms. Rothschild expresses affection for the decade, and Lara Jean’s father recommends Ken Burns’s documentary The War to her if she is interested in World War II. The exchange gives the historical period a specific point of entry: it is something to learn about through a documentary as well as an era that can prompt fondness and conversation.

The scene also distinguishes historical interest from the romantic nostalgia Lara Jean voices elsewhere. At Starbucks, she imagines dating as it was in the 1950s: a sequence of casual outings, rather than an immediately serious relationship. Her examples are drive-in movies and sock hops, and she describes the old-fashioned arrangement as appealing while worrying about the heaviness of breakups. The reference to the 1950s is not the same as the novel’s reference to World War II, but both place the characters’ present-day relationships beside an imagined past that offers alternative social scripts.

The Past as a Shared Social Setting

The historical period also informs a USO dance at a nursing home. The event gives the characters a setting shaped by a remembered wartime era, while the evening itself belongs to Lara Jean’s contemporary life: she helps organize the party, dances with John, and leaves buoyed by how well it has gone. The contrast makes the past more than background decoration; it supplies a social form through which present relationships can be experienced and remembered.

After the dance, Lara Jean sees Genevieve and Peter approaching with Genevieve’s arm linked through his. The sight makes the past year seem to vanish, as though she and Peter had never happened. Her description of the moment as a time machine turns historical imagery into a way of registering emotional recurrence: the period setting has ended, but an old relationship and its hurt feel abruptly restored.

Narrative Significance

World War II and the surrounding period references provide a vocabulary for thinking about memory, romance, and historical distance. The documentary suggestion treats the era as an object of inquiry; affection for the 1940s and the USO dance make it socially and aesthetically present; Lara Jean’s imagined 1950s dating customs show how the past can also become a model for present choices. These references remain distinct rather than collapsing into a single historical setting.

The novel’s use of the past is therefore less an account of wartime events than a contrast between historical periods and the characters’ immediate experience. Old-fashioned rituals can seem to promise a gentler way of approaching love, but the dance’s emotional aftershock shows that period atmosphere cannot keep earlier conflicts at a distance. A night shaped by nostalgia leads Lara Jean straight back to the unsettled present.
