Despite Carter's worries about the school's training materials, he believed that the international military education and training provided by the School of the Americas, among other institutions, was critical to furthering "the national interests of the United States". He considered the training conducted in Panama to be essential because it enhanced American "access to the politically influential leadership" of the Panamanian National Guard and instilled in its personnel "attitudes favorable to the United States". Further, he believed the training served to "increase respect for United States foreign policy goals and the United States concept of military-civilian relationships at the national level". To justify his decision to "provision international military education and training" to Panama in 1980, Carter argued that not doing so would "endanger the future operation" of the School of the Americas and the Inter-American Air Force Academy. Training manuals suspended under Carter were re-introduced into the school's curriculum under the Reagan Administration in 1982.
