More particularly he reminds his countrymen of a solemn caution whereby he warns them that if the methods used towards the Algerian people remain unchanged, colonization will end in a blood bath. Tocqueville includes in his report on Algeria that the fate of their soldiers and finances depended on how the French government treats the various native populations of Algeria, including the various Arab tribes, independent Kabyles living in the Atlas Mountains and the powerful political leader Abd-el-Kader. In his various letters and essays on Algeria, Tocqueville discusses contrasting strategies by which a European country can approach imperialism. In particular, the author differentiates between what he terms "dominance" and a particular version of "colonization". The latter stresses the obtainment and protection of land and passageways that promise commercial wealth. In the case of Algeria, the Port of Algiers and the control over the Strait of Gibraltar were considered by Tocqueville to be particularly valuable whereas direct control of the political operations of the entirety of Algeria was not. Thus, the author stresses domination over only certain points of political influence as a means to colonization of commercially valuable areas. 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. In 1856, Tocqueville published "The Old Regime and the Revolution". The book analyzes French society before the French Revolution—the so-called Ancien Régime—and investigates the forces that caused the Revolution. Tocqueville was quoted in several chapters of Toby Young's memoirs "How to Lose Friends and Alienate People" to explain his observation of widespread homogeneity of thought even amongst intellectual elites at Harvard University during his time spent there. He is frequently quoted and studied in American history classes. Tocqueville is the inspiration for Australian novelist Peter Carey in his 2009 novel "Parrot and Olivier in America".
