The cable news wars are heating up. On Wednesday, Fox News aired a promo that took a shot at MSNBC for its connection to embattled war correspondent Peter Arnett. The clip showed Arnett's controversial interview on Iraqi TV, with the following narration: "He spoke out against America's armed forces. He said America's war against terrorism has failed. He even vilified America's leadership and worked for MSNBC. Ask yourself: Is this 'America's news channel?'" Fox reportedly ran the spot after MSNBC refused to correct information on its crawl about Fox's own scandal-ridden correspondent, Geraldo Rivera — who left Iraq after drawing a map in the sand indicating troop movement and location. My take? The world was a much nicer place when CNN was the only game in town.
