This AF&S symposium on the ethics of senior officer resignation in the United States includes a collection of four papers, each looking at principled resignation in different ways. Two authors, Dubik and Snider, believe principled resignation of senior military officers is sometimes justified, especially in wartime, where their inherent morals clash with their professional demands; these senior officer's ability to resign in protest distinguishes their service to this nation between stewards and servants. Conversely, Feaver and Kohn believe principled resignation is almost never justified as this action weakens the military profession and ultimately threatens national security. Further, the disastrous effects increase the ever present friction and mistrust in the civil-military process. Each author answers the question in the context of current American civil military relations and it is their hope that this symposium will lead to further discussions, research, and policies regarding the ethics surrounding the issue.
