Howard Zinn ask...How come so many people were so easily fooled?

If we don’t know history, then we are ready meat for carnivorous politicians and the intellectuals and journalists who supply the carving knives. I am not speaking of the history we learned in school, a history subservient to our political leaders, from the much-admired Founding Fathers to the Presidents of recent years. I mean a history which is honest about the past. If we don’t know that history, then any President can stand up to the battery of microphones, declare that we must go to war, and we will have no basis for challenging him. He will say that the nation is in danger, that democracy and liberty are at stake, and that we must therefore send ships and planes to destroy our new enemy, and we will have no reason to disbelieve him.
