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.
