Nations are not communities and never have been. The history of any country, presented as the history of a family, conceals the fierce conflicts of interest (sometimes exploding, often repressed) between conquerors and conquered, masters and slaves, capitalists and workers, dominators and dominated in race and sex. And in such as world of conflict, a world of victims and executioners, it is the job of thinking people, as Albert Camus suggested, not to be on the side of the executioners.

I've always resented the smug statements of politicians, media commentators, corporate executives who talked of how, in America, if you worked hard you would become rich. The meaning of that was if you were poor it was because you hadn't worked hard enough. I knew this was a lite, about my father and millions of others, men and women who worked harder than anyone, harder than financiers and politicians, harder than anybody if you accept that when you work at an unpleasant job that makes it very hard work indeed.

Why do we have to be a military superpower? Why can't we be a humanitarian superpower?

In the United States today, the Declaration of Independence hangs on schoolroom walls, but foreign policy follows Machiavelli.

The stories coming out of Iraq everyday - the violence, the chaos, the deaths of Americans, the deaths of Iraqis... Of course the deaths of Iraqis are not played up as much. But when they count the corpses they see women and children. We are constantly killing the people who are suspected of something. Now, in the United States or under any decent system of justice, you don't kill people on suspicion. That's what you do when you bomb a house because there are suspected leaders there. But we've been doing that again and again and the result has been a toll of thousands of civilians.

Human beings, whatever their backgrounds, are more open than we think, that their behavior cannot be confidently predicted from their past, that we are all creatures vulnerable to new thoughts, new attitudes. And while such vulnerability creates all sorts of possibilities, both good and bad, its very existence is exciting. It means that no human being should be written off, no change in thinking deemed impossible.

It is possible, reading standard histories, to forget half the population of the country. The explorers were men, the landholders and merchants men, the political leaders men, the military figures men. The very invisibility of women, the overlooking of women, is a sign of their submerged status.
