Mr Pompeo said "there's nothing imminent today", in response to a question about how anxious people should be over the escalating tensions. "But each time they test another missile, or if they should conduct a nuclear weapons test, they develop expertise, they expand the envelope, and so it is probably fair to say they are moving toward that at an ever-alarming rate".
North Korea said on Thursday that plans would be completed by mid-August to fire four intermediate-range missiles to land near the U.S. Pacific island of Guam, 3,500 km (2,175 miles) away.
When asked about how close the North was to being able to deploy a nuclear weapon that could hit the U.S., he said: "They're closer".

They said the United States and its allies can no longer afford to stand by as North Korea pushes ahead with the development of a nuclear-tipped intercontinental ballistic missile.

"It's hard to put a timeline to these things", Pompeo said.

In a separate interview on ABC News, Trump's national security adviser, H.R. McMaster, struck a similar tone. "But we're taking all possible actions short of military action to resolve this very grave threat to the United States and the world", the lieutenant general said, citing diplomatic efforts, increased sanctions and increased pressure.
"Our response is we're prepared militarily to deal with this if necessary".
Referring to Kim, Trump added: "If he utters one threat. or if he does anything with respect to Guam or any place else that's an American territory or an American ally, he will truly regret it, and he will regret it fast". "But the goal of capable, ready forces is to preserve peace and prevent war. And so this is why what Kim Jong-un is doing is very, very unsafe".
