When someone gets mugged on your street, you can consider taking precautions. If your response is to roll out half a mile of barbed wire, electric fencing, and landmines all through the perimeter of your property, I would say that is absolutely 'upplaying' the actual level of threat.
Most Americans' understanding of the actual threat posed to the US by NK is ludicrously upplayed. NK is a credible offensive threat to SK, but that's a very limited problem for anyone living in Nashville, Tennessee.
Perhaps TN is just a radically different world, I'd frankly believe it, but I haven't seen anything too significant at all. The last time people were really concerned about NK for like... 3 days, I think it was ~2012 or so.
I wasn't criticizing the blog post, I was responding to a comment in this thread that claimed that for some strange reason the danger of NK is systemically underplayed by the media.
I argue that no, the media more typically overplays it, much like it overplays the threat from other non-peer nations. I'm assuming you don't feel like the news is telling you that Iran is a threat either... Which would put you in an informed minority.
