Political Science is not Physical Science; but Fukuyama tries his best to come up with general principles to understand politics.
Continuing with his apology of liberal democracy, following the steps of his mentor Samuel Huntington, Fukuyama in a tour de force, accomplishes goals. Using his extensive historical knowledge on political systems, from his ancestors in Japan, and other areas of the world he presents a compelling case on the existence of natural processes behind historical vicissitudes. There are at least two preconditions for all human societies, first kin feelings and ideas, then those that come from gift giving, to members of other families.
With these two forces he tries to make a theory of social power system formation.
Starting with hunter gatherers, he ends up with Washington D.C., in his view, the most advanced form of liberal democracy. In the case of Mexico, because it is my birth place, I find an astute view, which cleared my subjective gaze. There is a party which came out of at least four centuries of battles. These battles are not over, and Professor Fukuyama, would be the first to acknowledge the wealth of information coming out of that process. In his view, the lack of nation building wars with people outside the territory, produced a weak state. That state has not yet produced an advanced liberal democratic state as in the US.
The weak Mexican state is being tested today, by the main opposition political force, Morena, The leader, Andrés Manuel López Obrador, aka AMLO, is calling for president Enrique Peña Nieto's resignation.
After reading Fukuyama, I am convinced Mexico is strong enough to go through these difficult times, as it has happened in the past.
