It’s Not Too Late on North Korea

August is also when the United States and South Korea conduct major joint military exercises, which always set Pyongyang on edge. In August 2015, tensions escalated into cross-border artillery exchanges after two South Korean soldiers were wounded by land mines laid by North Korea. This juxtaposition of tough sanctions and military exercises has predictably heightened North Korea’s threats.

.. We have long lived with successive Kims’ belligerent and colorful rhetoric — as ambassador to the United Nations in the Obama administration, I came to expect it whenever we passed resolutions. What is unprecedented and especially dangerous this time is the reaction of President Trump. Unscripted, the president said on Tuesday that if North Korea makes new threats to the United States, “they will be met with fire and fury like the world has never seen.” These words risk tipping the Korean Peninsula into war, if the North’s leader, Kim Jong-un, believes them and acts precipitously.

Either Mr. Trump is issuing an empty threat of nuclear war, which will further erode American credibility and deterrence, or he actually intends war next time Mr. Kim behaves provocatively. The first scenario is folly, but a United States decision to start a pre-emptive war on the Korean Peninsula, in the absence of an imminent threat, would be lunacy.

.. History shows that we can, if we must, tolerate nuclear weapons in North Korea — the same way we tolerated the far greater threat of thousands of Soviet nuclear weapons during the Cold War.

.. First, though we can never legitimize North Korea as a nuclear power, we know it is highly unlikely to relinquish its sizable arsenal because Mr. Kim deems the weapons essential to his regime’s survival.

.. By most assessments, Mr. Kim is vicious and impetuous, but not irrational.

.. John Kelly, Mr. Trump’s chief of staff, must assert control over the White House, including his boss, and curb the Trump surrogates whipping up Cuban missile crisis fears.

.. Fourth, we must continue to raise the costs to North Korea of maintaining its nuclear programs. Ratcheting up sanctions, obtaining unfettered United Nations authority to interdict suspect cargo going in or out of the North, increasing Pyongyang’s political isolation and seeding information into the North that can increase regime fragility are all important elements of a pressure campaign.

Report: H.R. McMaster ‘Increasingly Volatile’ and ‘Frequently Blows His Top’

“McMaster, whose temper is legendary, frequently blows his top in high-level meetings,” the report notes, citing national security leaks that he believes undercut his authority. McMaster and Steve Bannon also clashed with each other in front of the president during a reported meeting about a strategy on Afghanistan.

Reports Thursday revealed that McMaster concluded that former National Security Adviser Susan Rice did nothing wrong, amidst questions about her decisions to unmask the identities of Trump transition officials communicating with Russians.  A letter from McMaster to Rice also surfaced, showing that he assured her that her security clearance would remain intact.
