From a Wall Street Journal column by Gerard Baker headlined “Hamas Defenders Wield Words as Weapons”:

John F. Kennedy said of Winston Churchill that he “mobilized the English language and sent it into battle.” From Pericles to Abraham Lincoln, words have often been as effective as armaments in shoring up a people’s defenses, reinforcing an army’s resolve, or inspiring a unit’s bravery.

But in war, as in peace, words can also be used to demoralize and disorient. They can be used—and have been—more deviously by the enemy, and its quill-, microphone- and laptop-carrying enablers and propagandists, to obfuscate and confuse, to seed doubt in a just cause.
