North Korea ‘crisis’ is surely more bluster than threat

Although it has involved disturbing events — ballistic missile launches, nuclear weapons tests, military exercises, inane bombast — the North Korean “crisis” of recent months is largely an invented one.
A year ago, the probability that North Korea would fire a nuclear-tipped missile at the US was essentially zero; the North did not have the capability to make such an attack. Pyongyang has since made technological advances.
