An alternative perspective on North Korea from the Cato Institute:
The North Koreans have been busy, testing a nuclear weapon and shooting off missiles. It seems that nothing upsets North Korea more than being ignored.
…
However, this really is all old news. Although the nuclear test reinforces the North’s irresponsible reputation, the blast has little practical importance. North Korea has long been known to be a nuclear state and tested a smaller nuclear device a couple years ago. The regime’s missile capabilities also are well-known.
