"In the decades after the Korean War, the ROK-US alliance has been the guardian of peace and prosperity on the Korean Peninsula," Kang told the troops. "For our two nations to go together... we must resolve our common threat. That is rapidly the growing threat posed by North Korea's nuclear and missile programs," Kang said.

"The ROK-US alliance stands at a critical juncture to address this existential threat from North Korea and to ensure durable peace and stability on the Korean Peninsula," she added.

The policymaker voiced confidence that Seoul and Washington will achieve their shared goal through a strong alliance and joint defense posture.

Her trip to the US troops comes ahead of President Moon Jae-in trip to Washington to meet with his US counterpart Donald Trump later this week. Kang expected to see the two will discuss "big pictures" in dealing with the North's nuclear issue.

"Four days from now, our two presidents will have their first meeting in Washington D.C. My president will express his appreciation for the solid ROK-US alliance and your indispensable contribution," the minister emphasized.

"Our two leaders will discuss joint strategy on furthering our comprehensive strategic alliance. They will also be drawing big pictures on how best to address the North Korean nuclear and missile threats," she added. (Yonhap)
