Its latest missile test reached an altitude of 2,000km and travelled a lateral distance of 800km before dropping into the Sea of Japan. Working to those figures it is said to have a range of 4,000km, but it could be more.
Experts are said to be reviewing the two previous "failed" launches to try to discover whether this is a new type of missile with a more advanced propulsion system than previously observed.
A range of 4,000km puts the whole of China. Japan and the Philippines, as well as some US overseas territories and bases, under threat.
It is time to talk to Kim and his mates, and I mean sit round a table and thrash things out properly without all the threats of this and that. If he goes off on one in a fit of pique we could all be for it.
