A volunteer army is the only proper, moral—and practical—way to defend a free country. Should a man volunteer to fight, if his country is attacked? Yes—if he values his own rights and freedom. A free (or even semi-free) country has never lacked volunteers in the face of foreign aggression. Many military authorities have testified that a volunteer army—an army of men who know what they are fighting for and why—is the best, most effective army, and that a drafted one is the least effective.
