 While a civil disobedient does not necessarily oppose the regime in which she acts, the revolutionary agent is deeply opposed to that regime (or a core aspect of that regime). Revolutionary agents may not seek to persuade others of the merits of their position – communication is usually not their primary aim, although they convey the urgency of a regime change. When revolution is called for, such as under colonial occupation, there is no need to justify constrained acts of protest like civil disobedience. Indeed, more forceful resistance can be justified as we pass into the realm of just war theory (Buchanan 2013; Finlay 2015). This is not to say that all violent tactics, including terror, are permissible, since the use of violence must not only pursue a just cause but also accord with proportionality and necessity (i.e., be undertaken in last resort and with a reasonable chance of success). As will be discussed in the next section, revolutionary activists and thinkers like Frantz Fanon (2004, ch. 1) and Gandhi disagreed about the effectiveness of violence in emancipatory struggles, but not about its justifiability, as Karuna Mantena (2018, 83–4) has shown.
