The "shock and awe" portion of the U.S.-led campaign in Iraq kicked off Friday afternoon — and it's safe to assume the entire planet was glued to their TV sets. MSNBC's Peter Arnett, one of the few remaining journalists still in Baghdad, referred to the air strikes as much more intense than those he witnessed during the 1991 Gulf War. Later, an emotional Tom Brokaw broke down on air after the mother of one of the U.S. Marines killed in combat called into the program and cautioned the news media to remember the toll war takes on servicemen and their families. It was an extraordinary moment in a day full of them.
