  Yoon has expressed active support for the possibility of South Korea having indigenous nuclear weapons. The Carnegie Endowment for International Peace referred to his policy as "nuclear populism." Some research shows that nationalist attitudes and anti-American sentiment are prevalent among supporters of an indigenous nuclear arsenal.
  
  On 22 September 2021, Yoon stated that he would ask that the United States redeploy tactical nuclear weapons in South Korea if there is a threat from North Korea. Nuclear weapons have not been deployed by the U.S. in South Korea since the early 1990s after an agreement with Russia and in an effort to ease tensions between North and South Korea. Speaking for the United States, U.S. Deputy Assistant Secretary of State for Japan and Korea Mark Lambert rejected Yoon's call for the re-nuclearization of South Korea and said the proposal was against U.S. policy.
  
  On 12 November 2021, Yoon indicated that he would be open to more U.S. THAAD missile deployments in South Korea.
