I was surprised to read the NPR is regarded as relatively unbiased as their Middle East coverage seems designed to make Americans think that military intervention is a moral necessity--without balancing that supposed necessity against the human costs to those involved, including civilians in those lands.
And it's really easy to say war is a moral necessity when we have what is in effect a poverty draft. Elites are vastly underrepresented and when relatively well-off people enlist, they get safer jobs
Here is a five-year-old interview with a former NPR employee who regards their foreign policy coverage as much like Pentagon press releases: https://current.org/2016/03/a-critic-sees-pro-government-bias-in-nprs-reporting/.
My own sense from listening to their foreign policy reports today, in 2021, is that NPR is indeed biased in a hawkish direction.
