["Developing World Bioethics, EarlyView. ", "\nABSTRACT\nMilitary clinicians in disaster relief must treat health diplomacy not just as an operational tool but as a potential ethical obligation that actively prevents the political misuse of healthcare in situations of acute ethical tension. In settings where host nation military actors may threaten vulnerable populations, clinicians assume dual roles as caregivers but also as ethical diplomats often acting as an advocacy for at risk groups. This paper argues that military clinicians must treat health diplomacy as an active ethical responsibility rather than solely a neutral operational function. It suggests it is essential to prevent the political exploitation of healthcare and protect vulnerable groups in unstable and challenging environments. The paper uses an adapted four‐pillars framework to analyse challenges of impartiality, host‐nation influence and ethnic bias. It examines how clinicians negotiate complex health‐diplomacy environments, especially where vulnerable groups may face racially motivated harm."]
