Tocqueville argued that though unpleasant, domination via violent means is necessary for colonization and justified by the laws of war. Such laws are not discussed in detail, but given that the goal of the French mission in Algeria was to obtain commercial and military interest as opposed to self-defense, it can be deduced that Tocqueville would not concur with just war theory's "jus ad bellum" criteria of just cause. Further, given that Tocqueville approved of the use of force to eliminate civilian housing in enemy territory, his approach does not accord with just war theory's "jus in bello" criteria of proportionality and discrimination.
