They do more stories than just the sensational or anti-American ones they do. They also give more acceptable reasons for criticizing the USA.
They already do criticize the NDAA, Drone Warfare and the darker or more controversial parts of US foreign policy that is
arguably justified.
They do have some points, and I will admit I do have a degree of trust torwards RT to report on the more unseedly parts of US policy but what they
could do to be truly reliable news source is not to interview people like globalresearch.ca or Alex Jones. Also do not whitewash everything Putin or China or US enemies does.
Also it would have been better if some of their newcasters with controversial views such as Abby Martin of breaking the set don't become conspiracy theorists. They could still question 9/11 or criticize the US response to it, but on grounds of "blowback" or "anti-imperalism" over conspiratorial trutherism.
