They sought the foreign assistance blindly, and the continuing domestic political struggles as well as the external debt also became the reasons that made the economic development worse than ever, and eventually resulted that the U.S. government took charge in the Dominican Customs.
Though the political intervention of U.S. made the country was garrisoned by the U.S. navy, the government of the United States also tent to set up a new system in local armed troop which was organized with police in order to replace the old one, and named the new guards as Guardia Nacional Dominicana. However, the program was difficult to practice because there were the military and the police existing in Dominican Republic, and they played the important roles in the Trujillo Era.
This thesis not only describes the cause and the effect of the dictatorship of Trujillo, but also finds the reason why the police became the ruling tool. Strictly speaking, the attitude and the role of the United States is another key reason to explain the later military and police training in the Dominican Republic and even in all the Latin America. Otherwise, the contents involve the analysis of the subordination between the military and the police, and review the defect of the police system in Latin American, it also include the survey of administrative structure of the democratic development countries.
