Joseph Dunford puts on his hat during a refueling stop at Air Base in Fussa, Japan, Sunday, Aug. 13, 2017. "He conducted two in July, so it wouldn't surprise me if there was another missile test".
"We're not closer to war than a week ago but we are closer to war than we were a decade ago", McMaster said, adding that the Trump administration is prepared to deal militarily with North Korea if necessary.
Moving forward, he said President Trump's tough talk and global unity against North Korean leader Kim Jung-un is working.
He said President Trump was just trying to give the country's people hope when he floated the idea on Friday that the USA would take military action after condemning Venezuelan leader Nicholas Maduro for human rights abuses and calling for him to hold "free and fair elections".
Mr Pompeo said "there's nothing imminent today", in response to a question about how anxious people should be over the escalating tensions. The CIA chief described Kim as "rational" and responsive to "adverse circumstances".
CIA Director Mike Pompeo says Venezuela could "very much" become a risk to the United States.
The top USA military officer, Marine Corps Gen. Joseph Dunford, is traveling in Asia and expected to meet with leaders in South Korea, Japan and China.
"We're all looking to get out of this situation without a war", Dunford said.
Friday: The US president warns that military solutions are "locked and loaded" should North Korea "act unwisely".
Pompeo said the rhetoric from Trump was geared at sending a message to North Korea and letting the isolated nation know that the USA policy of "strategic patience" had come to an end. China is the North's biggest economic partner and source of aid, but says it alone can't compel its wayward ally to end its nuclear and missile programs.
"Ideally, I'd love a denuclearized North Korea, but as I learned when I went there and had some pretty intense dialogue with them, that is a nonstarter with them", Clapper, who served under former President Barack Obama, told host Jake Tapper on CNN's "State of the Union". It also said that the two "reiterated their mutual commitment to denuclearization of the Korean Peninsula".
National security adviser H.R. McMaster said Trump has asked for a report on what could happen next in the country.
North Korea is thought to have developed a miniaturized warhead, and a more advanced intercontinental ballistic missile, that would enhance its ability to deliver a nuclear payload against the U.S.
USA intelligence does not indicate an imminent nuclear war with North Korea, the chief of the Central Intelligence Agency said Sunday, after a week of bellicose rhetoric between the two sides. In response, North Korea announced a detailed plan to fire ballistic missiles towards Guam, a USA territory in the Pacific.
Trump has responded to North Korea's threats with his own fiery rhetoric.
Pompeo told Fox News Sunday that when U.S. President Donald Trump raised the possibility of military intervention in Venezuela, Trump was trying "to give the Venezuelan people hope and opportunity to create a situation where democracy can be restored".
