If the topic interests you, The Atlantic has a decent article on what National Security Advisor H.R. McMaster believes North Korea’s intentions are in creating a nuclear missile capability. McMaster doesn’t buy the notion that it exists, as claimed, to deter a U.S. invasion and regime change.
It is his view the program exists to create a nuclear blackmail ability in the service of an overpowering desire to unify the Korean peninsula under Pyongyang’s rule. McMaster believes this desire drives the North Koreans in the same way it drove the North Vietnamese.
His view causes him to urge a more hawkish stance vis-a-vis North Korea. I find his reasoning persuasive, check out The Atlantic article.
The other DrC suggests I add a reminder of the recent announcement that North and South Korean athletes will march in together at the summer Olympics held in SK this summer. Such cooperation has not been the norm of late, and its meaning is unclear.
