The term "diplomat" refers to a professional involved in the art and practice of diplomacy, focusing on strategic negotiation and statecraft. Authors such as François de Callières emphasized the importance of historical knowledge and professional training, arguing that diplomats must understand the "network" of international relations and prioritize their nation's interests.
Walter Alison Phillips discussed the changing role of the diplomat in modern times, contrasting current demands with 18th-century practices. Frederick Palmer portrayed diplomats as advocates for peace, while W. L. Courtney presented a more skeptical view, associating the profession with deception. These viewpoints together illustrate the diplomat as both a strategist and a specialized practitioner, maneuvering through intricate political environments to achieve national objectives.
