U.S. intelligence agencies believe North Korea has increased production of fuel for nuclear weapons at multiple secret sites in recent months and may try to hide these while seeking concessions in nuclear talks with the United States, NBC News quoted U.S. officials as saying.
We have work to do before ruling out war to destroy Kim's nuclear program.
UPDATE: Secretary Mattis confirms the primacy of diplomacy:
And regarding the Korean Peninsula situation, our diplomats are firmly in the lead, and aligned with the agreement signed by President Trump and Chairman Kim at their summit earlier this month. As our diplomats work to bring this agreement to fruition, the U.S. military, in close coordination with our allies and partners, continues its clear-eyed approach, supporting international sanctions and multiple unanimous U.N. Security Council resolutions.
For now. Mattis isn't the sort who neglects being able to kill everyone in the room, if necessary.
