It is widely held that violent revolution can be justified to end tyranny. It is equally widely held that foreign intervention is not justified to end tyranny. Intervention is justified, if at all, in a much narrower range of cases – perhaps to halt massacre or genocide, but not to end ‘ordinary’ oppression. On this view, state oppression may be sufficient to furnish internal revolutionaries with a just cause for violence, but simultaneously insufficient to generate a just cause for outside parties to do the same. Can this difference be justified?
