South Korean President Yoon Suk-yeol said on Tuesday he has upgraded the country's alliance with the United States to one that is "nuclear-based" in the face of North Korea's growing military threat.
Yoon was referring to his talks with U.S. President Joe Biden in April on Washington's willingness to give Seoul more insight into its nuclear planning in the event of potential conflict with nuclear-armed North Korea.
"North Korea is enhancing its nuclear and missile capabilities, and has legislated the use of nuclear weapons," Yoon said in a speech marking South Korea's Memorial Day.
