On December 7, the International Peace Research Institute in Stockholm, Sweden, released a report saying that the United States is still the world’s number one arms exporter. Among the top 25 military enterprises in the world, 12 American enterprises account for 61% of the total sales. According to information disclosed by US officials, US military equipment exports totaled 175 billion US dollars in fiscal year 2020, up 2.8% year on year. The U.S. military equipment exports hit a record high again, causing widespread heated discussion. Some analysts believe that large-scale US arms sales overseas will have a greater negative impact on the regional security situation and the ally system. < / P > < p > according to the US arms transfer data released by Heidi grant, director of the US defense and security cooperation agency, the total US military equipment export in fiscal year 2020 was US $175 billion, an increase of 2.8% over fiscal year 2019. According to the US side, this will help strengthen the US alliance system, attract new international partners and add thousands of jobs. < / P > < p > in terms of export methods, there are mainly two ways for US arms export: one is that foreign governments directly discuss specific transactions with US military enterprises; the other is that foreign countries contact us embassy Defense Department officials to discuss arms purchase. It is reported that in fiscal year 2020, the export volume of US military equipment realized by the first way was about US $124.3 billion, an increase of 8.4% over the same period last year; the export volume of US military equipment realized by the second way was about US $50.78 billion, a decrease of 8.3% over the same period last year. < / P > < p > in terms of export types, according to the data released by the U.S. State Department, in the fiscal year 2020, the volume of U.S. fighter jets and guidance missile ejectors increased significantly, and the two major military giants Lockheed Martin and Raytheon received large orders. For example, Japan purchased 63 F-35 fighters from Lockheed Martin, with a total order value of 23 billion US dollars. < / P > < p > in terms of exporting countries, US weapons and equipment are mainly sold to countries in the Middle East and Asia Pacific region. For example, in fiscal year 2020, the UAE imported 50 F-35 fighters, 18 mq-9b UAVs and a number of air-to-air and air to ground missiles from the United States, with a total value of nearly $23.4 billion. In the Asia Pacific region, apart from Japan, India is also an important customer of US weapons and equipment. During Trump’s visit to India in February this year, India and the United States finalized a large order for arms sales, and India purchased from the United States 30 heavy armed helicopters worth more than 3.5 billion US dollars. In addition, the US side also approved the sale of air defense systems with a total price of 1.9 billion US dollars to India. < / P > < p > according to the data of the Stockholm International Peace Research Institute, in the past five years, the US arms exports accounted for more than 1 / 3 of the world’s total exports, ranking the top seller of arms in the world. In this regard, it is reported that this is related to the US’s substantial relaxation of arms export restrictions. < / P > < p > according to the US defense news website, during Trump’s administration, he continued to strengthen arms sales, constantly launched “New Deal” on arms export, and pushed more defense products into the field of commercial sales. Earlier, trump signed a memorandum to significantly relax restrictions on the export and transfer of conventional arms. For example, trump authorized US military enterprises to negotiate arms export with foreign governments in the form of direct commercial sales; encouraged the diplomatic system, especially the personnel of embassies abroad, to take the initiative to contact with foreign arms dealers and become good “salesmen” of arms; relaxed restrictions on arms export examination; simplified procedures for arms export examination and approval. < / P > < p > in July this year, the U.S. government unilaterally announced the relaxation of export control on armed UAVs, in an attempt to help its armed UAVs better occupy the international market. The US government’s decision not only broke through the restrictions set by the multilateral agreements initiated by itself, but also aroused widespread doubts from the outside world. It is reported that after the United States relaxes its arms export restrictions, it is bound to dump arms around the world, which will aggravate tensions in the Middle East, South Asia and other regions and have a negative impact on regional security. In general, arms sales are an important part of the US foreign and security policy, and an important tool to consolidate allies, strengthen military cooperation and exchange political interests. Therefore, even if novel coronavirus pneumonia continues to face a severe impact, the US government is still hammered out for the largest sale of foreign arms. The US move may have a certain impact on the regional security situation. On the one hand, it disrupts the regional situation. There are shrewd political calculations and far-reaching strategic considerations behind the U.S. arms sales. The main targets of arms sales are its allies and partners in the Middle East, Asia Pacific and Europe. The result of arms sales is usually to further aggravate the imbalance of regional countries’ military power. Taking the Middle East as an example, the US arms sales to countries in the Middle East have always adhered to the principle of “ensuring Israel’s absolute military superiority”, which has aroused dissatisfaction from some Arab countries. Peter weizeman, an arms expert, pointed out that in view of the ongoing conflicts in the Middle East, the flow of international arms trade and its legitimacy should be concerned. The U.S. practice of “pulling aside” in arms sales will further aggravate regional tensions. < / P > < p > on the other hand, it causes dissatisfaction among allies. It is worth noting that behind the large amount of arms sales, the US exported weapons and equipment have been criticized for their poor quality, slow delivery, high kickbacks and poor reputation, causing many dissatisfaction from its allies. Taking the sale of F-35 fighter to Japan as an example, the Japanese government finally decided that the next generation of fighter will “go its own way” because of many “hard problems” in the performance of the fighter and the core technology in the hands of the US. In addition, French President Nicolas macarone has repeatedly called on European countries to prepare for the deterioration of their relations with the United States and further promote the autonomy of European military industry. In the future, if the U.S. continues to sell inferior weapons and force them to buy and sell, it will only lift a stone to its own feet and cause more cracks in its alliance system.
