Is the DP establishing the lack of coverage or simply supplying what the market demand of readers are?  I'm guessing the latter.  This nation is largely asleep, and they don't wake up until the issue explodes in their face.  Even then, they don't bother to dig into the "why", but they'd rather just be led around by the nose and let others do the thinking for them.

During the Obama era, there were 5 sanctions passed against N. Korea, with us a big part of the formulation of those sanctions.  There were numerous warnings as well.  It isn't until now, when their weapons are actually being tested and showing up on the news do Americans care.

N. Korea started their weapons development in the 1990's.  In 2002, the Bush admin released info that N. Korea had been doing this and was in violation of the treaty they signed.  And, we did a lot of nothing thanks to the average American asleep at the wheel.
