CIA Director Mike Pompeo said nuclear war with North Korea is "not imminent" but the hermit kingdom is moving toward putting a nuclear weapon on an intercontinental ballistic missile at an "ever alarming rate."

Pompeo said on "Fox News Sunday" North Korean leader Kim Jong Un will continue moving toward expanding his nuclear arsenal.

"I'm quite confident he will continue to try to develop his missile program, so it wouldn't surprise me if there was another missile test," Pompeo said.

When asked if Americans should be worried about a nuclear war starting between the United States and North Korea, Pompeo said, "There's nothing imminent today" that points toward that happening.

Pompeo said Kim isn't the crazy person many people make him out to be, and he believes the dictator will respond to President Trump's tough rhetoric.

"I would describe him as rational, he responded to adverse circumstances and, as the Trump administration continues to put diplomatic pressure on the regime, I'm confident he will see that and the people around him will see that," Pompeo said.

The ultimate goal for the Trump administration is a denuclearized Korean Peninsula, Pompeo said.

But, Trump is going to be very clear about what the ramifications are going to be if the regime doesn't bend to his pressure.

"The president has made very clear to the North Korean regime how America will respond if certain actions are taken," he said.
