 It does not follow, however, that joining the fight, once it has started, is unjustified whenever the initiation of the conflict was unjustified (Buchanan 2013). Whether various individuals are morally justified in joining the war effort depends upon whether they have morally acceptable reasons for doing so, not upon the morality or immorality of the actions others took to initiate the conflict. If that is the case, then the earlier suggestion that “the morality of revolutionary war” must be disaggregated into the morality of various parties is vindicated. The justification for initiating revolution will be different from the justification for joining a revolution. This point is not limited to revolutionary wars, but it may be more significant in the revolutionary case, if generally speaking the initiation of revolutionary wars is harder to justify than some interstate wars, especially wars of self-defense or defense of others against aggression.
