 In general, the institutionalist approach is favoured by indirect consequentialists and contractualists. Indirect consequentialists believe these institutions are justified just in case they will in fact have better long-run results than any feasible alternative institutions (see Mavrodes 1975; Dill and Shue 2012; Shue 2013; Waldron 2016). Contractualists believe these institutions ground or reflect either an actual or a hypothetical contract among states and/or their citizens, which specifies the terms of their interaction in war (see Benbaji 2008, 2011, 2014; Statman 2014).
