NSA McMaster: NKorea's ICBMs Pose 'Grave Threat' to US

North Korea poses a "grave threat" with its intercontinental ballistic missile program, National Security Adviser H.R. McMaster said in a new interview.

McMaster's appearance on MSNBC's "Hugh Hewitt" is slated to air Saturday morning. He spoke with Hewitt about the reclusive nation that is led by Kim Jong Un.

When asked to confirm the ICBMs North Korea has launched had the ability to land anywhere within the United States, McMaster said, "I'm not going to confirm it. But as I mentioned, whether it could reach San Francisco, or Pittsburgh, or Washington, how much does that matter, right? It's a grave threat."

McMaster noted Kim should also be sleeping with one eye open because he is a marked man across the globe.

"I think he should not be [sleeping easily at night] because he has the whole world against him, right?" McMaster said.

"He's isolated. He's isolated on this. Since 1953, the Korean peninsula has been in a state of armistice. The war never formally ended and there's been no aggression, no aggression from the United States, South Korea, any of our allies."

McMaster, who currently serves as a lieutenant general in the Army, noted Kim is leading "an authoritarian dictatorship that has existed since the end of World War II."
