It is commonly accepted that recourse to war is justifiable only as a last resort. If a situation can be resolved by less harmful means, then war is unjust. It is also commonly accepted that violent actions in war should be necessary and proportionate. Violent actions in war are unjust if the end towards which those actions are means can be achieved by less harmful means. In this article, I argue that satisfaction of the last resort criterion depends in part (...) upon the likelihood of success of non-violent alternatives to war, and that the actual and potential effectiveness of non-violent resistance means that the last resort criterion of the jus ad bellum and the proportionality criterion of the jus in bello are harder to satisfy than is often presumed.

Although the discussion about feasibility in political theory is still in its infancy, some important progress has been made in the last years to advance our understanding. In this paper, we intend to make a contribution to this growing literature by investigating the proper place of feasibility considerations in political theory. A motivating force behind this study is a suspicion that many presumptions made about feasibility in several current debates—such as that between practice-independence and practice-dependence, ideal and non-ideal theory, and (...) political moralism and political realism—are too rigid and underestimate the numerous different ways in which feasibility concerns may enter into our theorizing. To chisel out this feasibility space, our aim is to suggest two metatheoretical constraints on normative political principles as intuitively plausible, the so-called ‘fitness constraint’ and the ‘functional constraint’, through which we elucidate five central aspects for determining proper feasibility constraints of an account in political theory.

11 April 2013 marks the 50th anniversary of the papal encyclical, Pacem in Terris, a document that has exerted enormous influence on the doctrines of war and peace articulated by Roman Catholic and non-Catholic writers alike. The argument we make here is that in its understanding of human rights, international peace and philosophical anthropology, the encyclical in effect abandons the ?just war? teachings that had guided the church's view of human conflict for 16 centuries, and we argue that the departure (...) is a mistake.
