As a statement of intent, it was about as blunt as they get.

North Korea has developed nuclear weapons and will never give them up, its leader, Kim Jong Un, told the world last month.

The move was “irreversible,” he said; the weapons represent the “dignity, body, and absolute power of the state” and Pyongyang will continue to develop them “as long as nuclear weapons exist on Earth.”

Kim may be no stranger to colorful language, but it is worth taking his vow – which he signed into law – seriously. Bear in mind that this is a dictator who cannot be voted out of power and who generally does what he says he will do.

Bear in mind too that North Korea has staged a record number of missile launches this year – more than 20; claims it is deploying tactical nuclear weapons to field units, something CNN cannot independently confirm; and is also believed to be ready for a seventh underground nuclear test.

All this has prompted a growing number of experts to question whether now is the time to call a spade a spade and accept that North Korea is in fact a nuclear state. Doing so would entail giving up once and for all the optimistic – some might say delusional – hopes that Pyongyang’s program is somehow incomplete or that it might yet be persuaded to give it up voluntarily.
