According to the Tokyo News of Japan on January 4, under the threat of the DPRK's nuclear and missile weapons, South Korea's domestic discussions on nuclear weapons are on the rise. South Korean President Yin Xiyue, who attaches great importance to the US ROK alliance, took a cautious attitude towards this, but some members of the ruling party advocated that "it is necessary not to rely on the US' nuclear umbrella 'for national defense." Someone around the US military base in South Korea, which deployed nuclear weapons during the cold war, said with concern: "This will trigger an arms race in the entire East Asia." It was reported that the background of the incident was that North Korea launched about 70 ballistic missiles last year, And showed the attitude of preparing for the seventh nuclear test. Ukraine, which withdrew its nuclear weapons after the Cold War, was attacked by Russia, which also attracted attention. According to the report, the public opinion survey released by the South Korean think tank Eshan Policy Research Institute last May showed that 70% of South Koreans were in favor of nuclear armed forces. This proportion is far higher than 54% in 2018. Due to the holding of the US DPRK and ROK DPRK summit, the atmosphere of dialogue was high at that time. The Biden government of the United States has a negative attitude towards the re deployment of nuclear weapons to US forces in South Korea. At a press conference last October, U.S. Ambassador to South Korea Goldberg stressed that "in order to ease tensions, the focus should be on removing nuclear weapons." The report pointed out that South Korea's nuclear armed forces violated the NPT mechanism, which only allows the United States, Britain, France, China and Russia to have nuclear weapons, and it is difficult for the international community to understand. US Secretary of State Antony Blinken expressed concern in the middle of October last year: "This will lead to broader nuclear proliferation." (Outlook New Times)
