As speculation mounts that Kim Jong-un and Trump could meet this month, analysts say Pyongyang will continue to see nuclear weapons as a matter of survival

North Korea’s launch last week of a missile from a naval destroyer elicited an uncharacteristically prosaic analysis from the country’s leader, Kim Jong-un. The launch was proof, he said, that arming ships with nuclear weapons was “making satisfactory progress”.

But the test, and Kim’s mildly upbeat appraisal, were designed to reverberate well beyond the deck of the 5,000-tonne destroyer-class vessel the Choe Hyon – the biggest warship in the North Korean fleet.

His pointed reference to nuclear weapons was made as the US and Israel continued their air bombardment of Iran – a regime Donald Trump had warned, without offering evidence, was only weeks away from having a nuclear weapon.
