"The principle of compulsory service, embodied in the system of conscription, lias been the means by which modem dictators and military gangs have shackled their people after a coup d'état, and bound them to their own aggressive purposes. In view of the great service that conscription has rendered to tyranny and war, it is fundamentally shortsighted for any liberty-loving and peace-desiring peoples to maintain it as an imagined safeguard, lest they become the victims of the monster they have helped to preserve."
