WASHINGTON — Senior U.S. national security officials said Sunday that a military confrontation with North Korea’s is not imminent, but they cautioned that the possibility of war is greater than it was a decade ago.

CIA Director Mike Pompeo and Army Lt. Gen. H.R. McMaster, President Trump’s national security adviser, tried to provide assurances that a conflict is avoidable, while also supporting Trump’s tough talk. They said the United States and its allies no longer can afford to stand by as North Korea pushes ahead with the development of a nuclear-tipped intercontinental ballistic missile.

“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.

But he stressed that the U.S. is pursuing “a very determined diplomatic effort” led by Secretary of State Rex Tillerson that’s coupled with new financial sanctions to dissuade North Korean leader Kim Jong Un from further provocations.

“The U.S. military is locked and loaded every day,” McMaster said.
