One side or the other, I'd suggest that every individual regardless of their specific view to read as many publications as they can. 

NYTimes, Washington Post/Times, HuffPost, Conservative Tribune, Breitbart, CNN, RT, etc.

You can only learn more about the different sides the more you challenge yourself on every level of discussion.

With that said, I find the 'mainstream' news to indulge in a credibility-damaging amount of sensationalism. I'm not a fan of headlines due to their easily manipulated nature to express a misleading idea; the news is keenly aware of this. With regards to Korea, I find them a significant threat but not the threat the news would have you believe. The numerous failed missile tests lend to that idea and Vox's assessment of North Korea's nuclear range is mildly assessed as misleading.

It's the same with Russia. I generally enjoy 1791L's videos (at least within the videos detailing his personally stated viewpoints) for their tendency to lean less towards liberal bashing and a respectable attempt toward nuanced discussion.
