Whether Osama bin Laden is doing it cynically and has no interest in these matters, or whether he's doing it out of genuine conviction, his voice has a tremendous resonance throughout the Arab world. One editorial in a Lebanese paper said it is a matter of great humiliation for the Arabs that the only man who can outline, truthfully, what our humiliations are is an Arab who has to say it from a cave in a foreign country.

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.

In just one year in Bosnia, thirty of my colleagues died. There is a little Somme waiting for all innocent journalists.

How could believers, people who regard themselves as true Muslims, get on those planes, quoting the words of God delivered through the Prophet to themselves, knowing they were going to kill innocent people? They saw the other passengers on the plane. They could see the woman with her little daughter. They saw people making phone calls to their wives or their husbands. They knew who they were killing.

If it is bin Laden, he's a very intelligent guy. He's been planning his war for a long time. I remember the last time I met him in 1997 in Afghanistan. And bin Laden said to me "From this mountain, Mr. Robert, upon which you are sitting, we beat the Russian army and helped break the Soviet Union. And I pray to God that he allows us to turn America into a shadow of itself." When I saw the pictures of New York without the World Trade Center, New York looked like a shadow of itself.

Individuals in various countries like Egypt and Saudi Arabia listen to the tapes of bin Laden. They gather in groups of four or five. They feel they want to do something to express their support for what they've heard. The idea that they were taking orders is a particularly Western idea.

President Bush will come here and there will be new "friends" of America to open a new relationship with the world, new economic fortunes for those who "liberated" them.
