Adm Harry Harris Jr tells the House Armed Services Committee there's a prevailing view that Kim needs a nuclear arsenal to safeguard his regime. But Harris says Kim is after much more.
He says Kim's "long view" is reunification under "a single Communist system." Harris says any future talks with North Korea must be focused on ridding the peninsula of nuclear weapons.
Harris has been in uniform for nearly four decades. Hes led US Pacific Command since May 2015 and last week Trump announced he was nominating Harris to be US ambassador to Australia. The post requires Senate confirmation.
