“Even though anthropologists have shown that certain primitive peoples seem to be free from the desire for power, nobody has yet shown how their state of mind can be re-created on a worldwide scale so as to eliminate the struggle for power from the international scene. … International politics, like all politics, is a struggle for power.”

Context: It is a double-edged makeshift to entrust an individual or a group of individuals with the authority to resort to violence. The enticement implied is too tempting for a human being. The men who are to protect the community against violent aggression easily turn into the most dangerous aggressors. They transgress their mandate. They misuse their power for the oppression of those whom they were expected to defend against oppression. The main political problem is how to prevent the police power from becoming tyrannical. This is the meaning of all the struggles for liberty.

The Pathway of Peace (1923)
Context: Time has shown how illusory are alliances of great powers so far as the maintenance of peace is concerned.
In considering the use of international force to secure peace, we are again brought to the fundamental necessity of common accord. If the feasibility of such a force be conceded for the purpose of maintaining adjudications of legal right, this is only because such an adjudication would proceed upon principles commonly accepted, and thus forming part of international law, and upon the common agreement to respect the decision of an impartial tribunal in the application of such principles. This is a limited field where force is rarely needed and where the sanctions of public opinion and the demands of national honor are generally quite sufficient to bring about acquiescence in judicial awards. But in the field of conflicting national policies, and what are deemed essential interests, when the smoldering fires of old grievances have been fanned into a flame by a passionate sense of immediate injury, or the imagination of peoples is dominated by apprehension of present danger to national safety, or by what is believed to be an assault upon national honor, what force is to control the outbreak? Great powers agreeing among themselves may indeed hold small powers in check. But who will hold great powers in check when great powers disagree?.
