Famous quotes containing the word bombs:
“Today the discredit of words is very great. Most of the time the media transmit lies. In the face of an intolerable world, words appear to change very little. State power has become congenitally deaf, which is whybut the editorialists forget itterrorists are reduced to bombs and hijacking.”
—John Berger (b. 1926)
“Civilization is maintained by a very few people in a small number of places and we need only some bombs and a few prisons to blot it out altogether.”
—Cyril Connolly (19031974)
“We cannot be any stronger in our foreign policyfor all the bombs and guns we may heap up in our arsenalsthan we are in the spirit which rules inside the country. Foreign policy, like a river, cannot rise above its source.”
—Adlai Stevenson (19001965)
