On Sunday Report, CIA Director Tom Pompeo told Chris Wallace that there was no imminent threat of a nuclear exchange. However, he was quite unclear about what the CIA believes is N. Korea's delivery capability. He only stated that N. Korea has made significant progress.

On the other hand, Gordon Chang told Maria Bartiromo that N. Korea has a delivery system and nuclear warhead.

I don't know which to believe. The effective delivery of a nuclear weapon to its target is quite complex. The guidance system alone is an immense challenge. Why target Guam when Japan is only about 500-600 miles away? In any case, nothing's going to impede N. Korea's development of a deliverable nuclear weapon short of a US attack on N. Korea.
