The fourth hour of News War looks at media around the globe to reveal the international forces that influence journalism and politics in the United States. The lead story focuses on the new Arab media and its role in both mitigating and exacerbating the clash between the West and Islam. With a focus on Al Jazeera and how it has changed the face of a parochial and tightly controlled Arab media, this hour explores Al Jazeera's growing influence around the world -- from Muslim communities in Europe to the pending launch of a new English-language service that will be broadcast in the United States.
