A political cartoon about the East Saint Louis massacre of 1917. The original caption read, “Mr. President, why not make America safe for democracy?” That referred to U.S. President Woodrow Wilson’s catch-phrase (“The world must be made safe for democracy”) to convince the U.S. Congress to declare war on Germany, allowing the United States to become a combatant in World War I / credit: William Charles Morris for the New York Evening Mail
