Donald Trump and Kim Jong Un have very different objectives from their on-again, off-again negotiations. More work needs to be done to build trust and align the leaders on a basic common goal.
Every time North Korea needles the US with another provocation, it makes it harder for Donald Trump to mobilise the domestic support for a return to the negotiating table.
Without its communist Soviet-style economy, North Korea would just be South Korea.
North Korea and the US have again failed to reach an agreement – and South Korea is being left on the sidelines.
Any meaningful breakthrough in the relationship between the US and North Korea is once again stalled by the insistence on denuclearisation.
Research shows the news media often reproduce metaphors that frame North Korea as dangerous, provocative, irrational, secretive, impoverished and totalitarian.
Any meaningful way forward must be based on imagination and mutual understanding.
The new friendship between North Korea and Cuba is puzzling. The two countries should share values as socialist republics, but their brands of socialism are worlds apart when it comes to children.

The Pyongyang Declaration between the two Koreas is about much more than nuclear power – and leaves the US on the outer.

Novichok are a set of molecules that are some of the most deadly nerve agents ever developed. They are almost impossible to detect and clean up.
North Korea's infrastructure is in dire need of expansion and modernisation. This is where the South can help.
At this stage one can only judge the atmospherics and optics of the summit, and on that basis, Beijing and Pyongyang have plainly come out ahead, while Tokyo and Seoul seem to have been overlooked.
Looking at the agreement, it appears that Kim Jong-un has outmanoeuvred Donald Trump.
One noticeable omission was any mention of "complete, verifiable, irreversible denuclearisation" - whether this was strategy or capitulation on President Donald Trump's part remains to be seen.
Alongside denuclearisation, reunification is the biggest potential game-changer on the Korean peninsula. But it remains a pipe dream.
Kim Jong-un may be able to "chat" in English. That's not enough to understand Donald Trump.
Can decades of deadlock be broken by two of the world's most unpredictable leaders?
