We turn now over the debate of the proposed Islamic center and mosque near Ground Zero....The controversy has raised profound questions about religious tolerance and prejudice in the United States.

I'm thrilled to be joining the incredible team at ABC News. Being asked to anchor 'This Week' and the superb tradition started by David Brinkley, is a tremendous and rare honor, and I look forward to discussing the great domestic and international issues of the day.

But to be self-obsessed is simply not o.k. for the most important country in the world, the United States, which affects every other country in the world.

What we do and say and show really matters.

And then theres always the crying and the weeping that we hear-children, women, even men. And these images and these sounds are always with me.

Some people accused me of being pro-Muslim in Bosnia, but I realised that our job is to give all sides an equal hearing, but in cases of genocide you can't just be neutral. You can't just say, 'Well, this little boy was shot in the head and killed in besieged Sarajevo and that guy over there did it, but maybe he was upset because he had an argument with his wife.' No, there is no equality there, and we had to tell the truth.

We in the press, by our power, can actually undermine leadership.
