 The topic of revolution presents a fertile and challenging field for moral theory and applied or practical ethics—and one in which the greater part of systematic thinking remains to be done. Violent revolutions typically present the most serious and difficult moral issues. Until recently, the excellent work done by contemporary just war theories has not given the peculiar moral problems of revolutionary war the attention they deserve, but there is reason to believe that this deficiency will be remedied. Because the success of a revolution may depend upon whether there is intervention in support of it, a comprehensive theory of the morality of revolution should cohere with a theory of the morality of intervention (Buchanan 2016). Another topic that a comprehensive theory of just revolutionary war should address is the moral assessment of the international Law of Armed Conflict’s asymmetry with regard to the rights of combatants acting on behalf of states and revolutionary warriors. The Law of Armed Conflict assigns the latter the same legal duties as the former, but grants them a much leaner set of legal rights.
