South Carolina Sen. Lindsey Graham wants the Pentagon to pull the families of service members out of South Korea because he feels a military confrontation is coming with North Korea.

“We're getting close to military conflict because North Korea's marching towards the technology of [an intercontinental ballistic missile] with nuclear weapon on top that cannot only get to America but deliver the weapon,” he said on CBS’ “Face The Nation.”

“We're running out of time, Gen. [H.R.] McMaster said that yesterday. I'm going to urge the Pentagon not to send any more dependents to South Korea, South Korea should be an unaccompanied tour. It's crazy to send thousands of children to South Korea. I want them to stop sending dependents, I think it's now time to start moving American dependents out of the South Korea.”

North Korea tested a missile that landed in the Sea of Japan earlier this week, the hermit kingdom’s first weapons test in months. The test has caused new worries that a military confrontation between the U.S. and North Korea is brewing.

Graham said he’s worried another underground test of a nuclear bomb by the North Koreans would require an American military response.

“The policy of the Trump administration is to deny North Korea the capability to hit American with nuclear-tip missile. Pre-emptive war as last resort,” he said.

“That is becoming more likely as technology matures. Every missile test, every underground test of a nuclear weapon means marriage is more likely, I think we're really running out of time. The Chinese are trying, but ineffectively. If there is underground nuclear test then you need to get ready for a very serious response by United States.”
