The author argues that military preparedness and competitive armaments increase the risk of catastrophic war rather than securing peace, and urges instead creation of legal and diplomatic mechanisms to resolve international disputes supported by strong public opinion. He endorses immediate adherence to the existing World Court with reservations, conditional participation in the League of Nations to avoid automatic military or economic commitments, and pursuit of an international outlawry of war paired with disarmament conferences. The pamphlet stresses cultivating international understanding through education, cautions against unilateral arms buildups, and regards automatic sanctions as impracticable.
