 According to members of the Bolivian military quoted by the Wall Street Journal, authorities had questioned Morales' actions for some time.Morales had performed multiple actions that had offended officers within the armed forces, including glorifying Che Guevara after his guerrillas killed 59 Bolivian troops during their insurgency in the 1960s and forcing officers to attend the Anti-Imperialist Military Academy that was led by a convicted former rebel.General Tomás Peña y Lillo, who was chief of the Bolivian armed forces until 2010, stated that officers within the military were traditionally conservative and had refused plans proposed by Morales to be guided by Cuban military and intelligence agents, damaging Morales' hold of the military.
