Pacem in Terris §89

⁸⁹ The fact is that no one can be by nature superior to his fellows, since all men are equally noble in natural dignity. And consequently there are no differences at all between political communities from the point of view of natural dignity. Each State is like a body, the members of which are human beings. And, as we know from experience, nations can be highly sensitive in matters in any way touching their dignity and honor; and with good reason.
