According to the United States New York Times reported 3 days ago, Trump has issued instructions to the The Pentagon to make preparations for reducing the number of US troops in Korea. Several U. S. officials told the newspaper that Trump did not want to cut the size of the U. S. troops in South Korea as a bargaining chip with Kim Jeong-eun, the top leader of the North Korean leader, but if a peace agreement was reached, it was not necessary for the United States to continue to retain its troops in South Korea. Reported that Trump had decided to withdraw from South Korea, he did not think enough funds to maintain the garrison expenses. In addition, the US troops stationed in South Korea are mainly protecting Japan. The report also pointed out that some officials in the United States were worried that the reduction of the U. S. forces in the United States would weaken the Han - US alliance, in the imminent progress of the DPRK and US negotiations, or to cause anxiety in Japan. However, the United News Agency said 4, the Chief Secretary of Chong Wa Dae, Yin Yongcan, sent a message to the media on the same day, and the president of the national security room, Zheng Yirong, who was visiting the United States, had been on the phone with the White House core, clarifying that the report was not true. Zheng Yirong is now at the invitation of the US National Security Council to conduct a non public visit to the United States to discuss the DPRK summit talks. South Korean media said, Panmunjom declaration mentioned, such as the declaration of armistice, it is necessary to reduce the size of the current US forces in South Korea. However, Wen said on 2 July that the US forces still need to be stationed in South Korea after the peninsula is suspended and the mechanism is converted. Wen Yin believes that the US forces in South Korea are related to the ROK US alliance and have nothing to do with the signing of the peace agreement between the DPRK and the DPRK. The South Korean Daily said that although Chong Wa Dae has refuted rumours, news of the possible reduction of American troops in South Korea has emerged recently, and the topic has aroused great concern. It is pointed out that it is not impossible for Trump to reach the above instructions. As the DPRK enters the abandonment stage, the United States and the DPRK will turn from hostility to normal state relations, so the corresponding adjustment to the number and nature of the US troops in Korea is normal. After the DPRK abandoned its nuclear weapons, the DPRK and DPRK entered the stage of conventional arms reduction, and the US military issue in Korea would also be taken to the negotiating table. Yonhap believes that if the New York Times report is true, then Trump may want to reduce the issue of South Korean troops as a bargaining chip with Kim Jeong-eun. But there is also a point of view that Trump is more likely to bear more pressure on South Korea than to use it as a bargaining chip for the DPRK. Under the existing US South Korea agreement, South Korea needs to pay nearly half of the cost of the US troops, while the Trump administration hopes that the ROK will bear all US military spending. In addition to the issue of the US military presence in Korea, the suspension of the peninsula and the transformation of the mechanism may also lead to the US commitment to the South Korean nuclear umbrella. South Koreas East Asia Daily said the so-called nuclear umbrella commitment means that in the event of war, the United States will use intercontinental ballistic missiles, strategic bombers, strategic nuclear submarines and other nuclear combat forces to protect South Korea. The South Korean military has repeatedly said that the promise of nuclear umbrella is one of the key chips to curb North Korea and DPRK dare not use nuclear weapons. However, after the South Korean summit, the US and DPRK talks may also end satisfactorily. If the parties formally begin to discuss the peace agreement, it may lead to a dispute over the reasonableness of the commitment of the United States to the Korean nuclear umbrella protection, which does not exclude the possibility that the Korean government has put forward the useless theory of nuclear umbrella. At present, South Korea is still actively promoting the peninsulas suspension and mechanism transformation. Chong Wa Dae spokesman Kim Yi Qian 4, said in Yin day in the afternoon with Chinese President Xi Jinping on the phone, said the success of the South Korea summit talks can not be separated from the presidents full support and attention. In the process of the comprehensive denuclearization of the peninsula and the establishment of a permanent peace mechanism, we need constant attention and support from the Chinese side.
