NORTH KOREA

“So, if anything, maybe that statement wasn’t tough enough,” President Trump told reporters yesterday at his golf club in New Jersey, refusing to temper the comments he made Wednesday that North Korea would face “fire and fury” if it continued to issue threats against the U.S. and its allies, adding that “it’s about time that somebody stuck up for the people of this country and for the people of other countries.” Paul Sonne and Louise Radnofsky report at the Wall Street Journal.

“He’s not going to go around threatening Guam and he’s not going to threaten the United States and he’s not going to threaten Japan, and he’s not going to threaten South Korea,” Trump also told reporters, reiterating the seriousness of his warning against North Korea and its leader Kim Jong-un and stating that the U.S. retaliation for an attack on Guam would be “the likes of which nobody has seen before.” Peter Baker reports at the New York Times.

“We are preparing for many different alternative events,” Trump told reporters yesterday that the U.S. would reconsider its entire military presence in Asia as a consequence of the North Korea threat and “other reasons,” his comments coming just a few days after the Trump administration congratulated itself for passing a 15-0 U.N. Security Council Resolution imposing sanctions against the Pyongyang regime. Philip Rucker and Karen DeYoung report at the Washington Post.

Diplomatic efforts have “traction” and are “gaining results,” Defense Secretary Jim Mattis said yesterday, highlighting the efforts of Secretary of State Rex Tillerson and U.S. ambassador to the U.N. Nikki Haley, stating that his job is to be ready for conflict but adding that the “tragedy of war is well enough known,” the BBC reports.

China should stay neutral if North Korea attacks the U.S., Chinese state-run newspaper the Global Times said today, Ben Blanchard and James Oliphant reporting at Reuters.

“A pre-emptive war … would be catastrophic,” former national security adviser Susan Rice said yesterday, warning that the war of words between the U.S. and North Korea could move the nations closer to war but adding that she accepted that previous administrations had failed to stop North Korea from developing its nuclear arsenal.
