US National Security Adviser H.R. McMaster echoed the tenor of Pompeo's remarks, saying the threat posed by North Korea is "coming to a head", but adding in an interview on ABC, "we're not closer to war than a week ago".
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.
"The US military is locked and loaded every day", Mr McMaster said, repeating Mr Trump's threat.
"Our response is we are prepared militarily to deal with this if necessary".
When host Chris Wallace pressed him about how close North Korea is to being able to hit the USA mainland, Pompeo said that it was alarming but hard to define.
Clapper said on CNN that the rhetoric was having a destabilizing affect and could cause North Korean leader Kim Jong Un to decide to lash out.
Pressed on his "nothing imminent" statement, Pompeo said: "What I'm talking about is, I've heard folks talking about that we have been on the cusp of a nuclear war".

North Korea also claimed "no other country in the world was more transparent" about the development of their nuclear weapons. Last month, North Korea tested two ballistic missiles capable of reaching the United States.
"Trump is driving the situation on the Korean peninsula to the brink of a nuclear war, making such outcries as 'the US will not rule out a war against the DPRK (North Korea),'" KCNA said.
President Trump wrote on Twitter on Friday that U.S. "President Trump has made it clear that it is his intention to protect the American people". 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.
North Korean officials in turn have accused the USA leader of driving the Korean peninsula to the brink of nuclear war.
Both sides have used hostile rhetoric, with President Donald Trump threatening "fire and fury" on the North.
"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".
A Chinese state-run newspaper said on Friday that China should remain neutral if North Korea launches an attack that threatens the United States, sounding a warning for Pyongyang over its plans to fire missiles near Guam.
Now it was on countries like China and Russian Federation along with USA allies like South Korea and Japan to work in tandem to get nuclear weapons out of the region.
