The term "diplomacy" has been used in literature in a variety of ways, often straddling the line between high-level statecraft and the subtleties of personal interaction. In adventure narratives like Kipling’s Kim [1, 2], diplomacy is portrayed as a secret language of negotiation and cultural interplay, while on a more personal level, as in Dumas’s The Count of Monte Cristo [3, 4] and Christie’s mystery tales [5, 6], it becomes a natural instinct or a crucial tool for persuasion. Meanwhile, in works on strategy and politics—such as those by Herzl [7, 8] and Jomini [9, 10, 11, 12]—diplomacy is elevated to an art form essential to both military success and statecraft. Authors like Sinclair Lewis [13, 14, 15, 16, 17] and Santayana [18, 19] use the term with a satirical edge, exposing the tension between genuine skill and the superficial charm sometimes mistaken for true tact. Across these examples, diplomacy emerges as a multifaceted concept, reflecting both the grand maneuvers of history and the everyday negotiations of human relationships [20, 21].
