“Pacifists would do well to study the Siegfried and Maginot Lines, remembering that these defenses were forced; that Troy fell; that the walls of Hadrian succumbed; that the Great Wall of China was futile; and that, by the same token, the mighty seas which are alleged to defend us can also be circumvented by a resolute and ingenious opponent. In war, the only sure defense is offense, and the efficiency of offense depends on the warlike souls of those conducting it.” (George Patton, War As I Knew It, published 1947, page 238)
