Back during the Vietnam War, CBS News anchor Walter Cronkite went to South Vietnam to see for himself the state of the war. The report was uniformly negative which caused President Johnson to famously say "when you've lost Walter Cronkite, you've lost America".
Fast forward to 2011. There is no one quite the stature of Walter Cronkite anymore but Jon Stewart of The Daily Show will have to do. His report on Project Gunwalker, while comedy, skewers it more thoroughly than even Darrell Issa and Chuck Grassley have been able to do.
