The top Democrat on the Senate Armed Services Committee said South Koreans are “confused” and “a little bit shaken” by President Donald Trump’s rhetoric on North Korea.

Sen. Jack Reed (D-RI) on Monday spoke to reporters after returning to Washington, D.C., from a visit to South Korea and the Demilitarized Zone.

"I think they are confused and I think they are a little bit shaken because they understand that they would be in the line of fire if there's any contact between the United States and North Korea in terms of a kinetic military operation," he said.

Trump and North Korean dictator Kim Jong Un have engaged in a heated war of words in recent months, as tensions over the rogue nation's nuclear weapons program have escalated.

Trump has dubbed Kim “Rocket Man,” while Kim has called Trump a “mentally deranged U.S. dotard.”

Retired U.S. Navy Admiral Robert Natter said on "Happening Now" today that this is not a good situation.

He explained that the Obama administration and previous administrations "failed miserably" at using diplomacy to curb North Korea's nuclear ambitions.

He said the Trump administration must continue to look for a diplomatic solution, while also readying a military response.

"We are facing a dominant threat here. It's very serious. And guess who's holding the bag? The American people," Natter said. "This is not a good situation."
