Meanwhile, Twitter gave VP Mike Pence kudos for his stern demeanor in North Korea. I think you're not going to see him telegraphing how he's going to respond to any military or other situation going forward.

Tensions are running high around the Korean Peninsula amid speculation that the North might carry out an additional nuclear test or a long-range missile launch.

In a statement to the House of Commons on the recent global crises in Syria and North Korea, Mr Johnson said: "These disparate challenges incorporate one common theme". "Abandon your nuclear weapons".
President Donald Trump talked tough on the country's resolve, tweeting: "Our military is building and is rapidly becoming stronger than ever before". "I'm not like other administrations, where they say, we're going to do this in four weeks, and that doesn't work that way".
Fox News asked Trump about his plans for the Korean peninsula.
On Monday, Pence traveled to the tense Demilitarized Zone dividing North and South Korea, where he warned North Korea's leaders that after years of testing the US and South Korea with its nuclear ambitions, "the era of strategic patience is over".
"I said, 'Do you want on your resume that during your presidency the North Koreans developed a missile that could hit the American homeland with a nuclear weapon on top of it?' And he said, 'Absolutely not, '" Graham said.
"While all options are on the table", Pence said, "President Trump is determined to work closely with Japan, with South Korea, with all our allies in the region, and with China" to resolve the problem.
A Foreign Office spokesman told the Standard: "The projects we carry out in North Korea are part of our policy of critical engagement, and are used to promote British values and demonstrate to the North Korean people that engaging with the United Kingdom and the outside world is an opportunity rather than a threat".
The president's warning comes as a senior North Korean official has told the BBC, North Korea will continue to test missiles regularly and any military action against it by the United States would prompt "all out war". "They've all been outplayed by this gentleman and we'll see what happens".
