Kim Jong-un shows off ‘scary’ new Hwasong-16 nuclear missile

Headlines we'll never see:
"Australia shows off its scary new weapon"

Unless, of course, the article is about a new spin bowler with madder skills than Warnie.

The NK missiles themselves are fairly good based on the little info I have found. They have used existing tech from other countries and have successfully altered and combined it. I guess they maybe had foreign advisers helping to some degree but missile tech is very unforgiving. Get it even slighty wrong and BOOM.
Their nukes seem to be a bit unreliable but this is to be expected. Very precise timings are needed to get a good explosive yield. And making them smaller and lighter to go on top of missiles while still tough enough to survive the launch sequence is also difficult.
