War as a Sign of Impotence

From The Roots of Reconstruction:

War is a sign of impotence. A system or philosophy of life which has no power to convert becomes imperialistic. For the zeal and faith of peaceful missionary work it substitutes brutal terror. A failing faith resorts to war, because it lacks the contagion of faith and conviction and can only force men into its own system. War is the resort of those who lack true power and are declining.
