When you have a crime against humanity that is so awesome in scale and death, it is more than permissible to look around and say, who recently has been declaring war on the United States? Of course, the compass points straight to bin Laden.

We live in a society in the West, where, when men do violent things, they do them under orders. They are soldiers carrying out orders or mafia men carrying out killings for bosses. But the way things happen in the Middle East is not the same as in the West.

At the end of the day, bin Laden's interest is not Washington and New York, it's the Middle East. He wants Saudi Arabia. He wants to get rid of the House of Saud.

I suppose, in the end, we journalists try - or should try - to be the first impartial witnesses of history. If we have any reason for our existence, the least must be our ability to report history as it happens so that no one can say: 'we didn't know - no one told us.'

Bin Laden is not well read and he's not sophisticated, but he will have worked out very coldly what America would do.

And I think, in the end, that is the best definition of journalism I have heard; to challenge authority - all authority - especially so when governments and politicians take us to war, when they have decided that they will kill and others will die.

When I arrived in Beirut from Europe, I felt the oppressive, damp heat, saw the unkempt palm trees and smelt the Arabic coffee, the fruit stalls and the over-spiced meat. It was the beginning of the Orient. And when I flew back to Beirut from Iran, I could pick up the British papers, ask for a gin and tonic at any bar, choose a French, Italian, or German restaurant for dinner. It was the beginning of the West. All things to all people, the Lebanese rarely questioned their own identity.
