Two types of recruits are accepted by the UN Inspector Corps: those with a fanatic loyalty to the ideals of peace and world order, and those who are loyal to nothing but themselves. Rather than resign, he accepted punishment which assigned him to weeks of dull, filthy extra labor. He began a propaganda war against neighboring South Africa, promising the liberation of that strife-torn land.
