How dangerous is North Korea?

This week North Korea celebrated 75 years of communism with a military parade at which it unveiled an giant intercontinental missile. The heavily choreographed event featured all the pomp and circumstance the world has come to expect from North Korea's mass human performances. It also contained a surprisingly emotional speech from Chairman Kim Jong-Un, who at times wept as he spoke about the country's struggles. The country’s first military parade in two years signalled a shift back to the more aggressive stance it used to adopt before the now stalled nuclear talks with the Trump administration. So is there any hope that temporary thaw created enduring opportunities for engagement with the rest of the world - or are we seeing a return to past behaviour?
