As he has before,former PM Paul Keating often reveals more than he should when speaking on behalf of his masters. So it was in 1993 when he stupidly made public the Clinton Administration's views on Mahathir Moahamd (albeit ,possibly, in more colourful terms,which was probably what the US intended) and then again more recently when he revealed China's plans for the South China Sea and Eastern Europe.
He seems here to have done it again, where his main point , probably reflecting his current paymaster China's view, is that:
a) The West must not try to deprive North Korea of its nuclear weapons.
b) Doing so will make North Korea unstable, which will make South Korea open to attack
c) That the best policy is some form of detente, which the West had with the Soviet Union,which will allow North Korea to retain (and keep developing) its nuclear capability.
Of course, it will then follow that China will retain a capability, via North Korea, to keep the United States, Japan and South Korea, and all their allies in the Pacific off-balance as and when the need arises, easing the way for Chinese adventures in the Pacific ,and the South China Sea.
Keating has not the brains to conceive any of this.
He is clearly reading from a script given him.
