Sihai network integration: on July 8, 2016, the United States and South Korea officially announced that they would deploy Sade anti missile system in South Korea, South Korea claimed that Sade was deployed to prevent North Korea. North Korea also claimed that the United States deployed Sade in South Korea only against North Korea, but why did it cause strong dissatisfaction from China? What kind of threat does Sade pose to China?
Here we first want to know what Sade is. Thad is also called terminal high altitude area defense system. It is a land-based theater anti missile system under the United States missile defense agency and the United States Army. As a defense system specially used to deal with large-scale ballistic missile attacks, the terminal high altitude area defense system has the unique advantage of being a combat force while defending against the threat of large-scale missiles Provide more flexible use options. Its purpose is not to replace but to supplement mim-104 air defense missile, Navy aegis ballistic missile defense system, land-based midcourse defense system and early warning radars and sensors deployed by the United States around the world, so that the U.S. military has a multi-layer ballistic missile defense capability and is a strategic offensive weapon.
In other words, the Sade system is not only a strategic defensive weapon, but also a strategic offensive weapon. Compared with the Patriot anti missile system of the United States, although its name is not as loud as that of the patriot, it is better than the patriot in many aspects. It can intercept the altitude beyond the atmosphere, reaching 150 km, and is controlled by interceptor, vehicle mounted launcher, ground radar, and combat management, command and control , communication and information system (BM / C31). The interceptor is 6.17 meters long, with a maximum diameter of 0.37 meters, a takeoff weight of 900 kg and a maximum speed of 2500 meters / second. It uses direct impact to destroy the target. It mainly intercepts ballistic missiles with a range of 3500 km. The maximum interception height and distance are 150 km and 300 km respectively, and the defense radius is about 200 km. Because of its high technical starting point and strong risk, the 'Sade' system is the only ground-based system that can intercept ballistic missiles both inside and outside the atmosphere, so its combat technical performance has its own unique characteristics.
The nuclear strategy formed between our country and other nuclear powers is to ensure the destruction of each other. It means that all the nuclear powers in the world have a reliable second nuclear strike capability, that is, after the other party carries out the nuclear strike first, they can still survive and have the nuclear retaliation ability to completely destroy each other. Therefore, any party launching a nuclear attack will definitely encounter retaliatory response. As long as this' stable peace of terror 'is maintained, both sides will be deterred from launching strategic nuclear attacks and avoiding nuclear war. Otherwise, both sides may die together.
Therefore, once the United States has mastered the practical missile defense system, it will be very difficult for China's missiles to pose a security threat to the United States. As a result, after China's nuclear attack on the United States, the United States will no longer worry about China's nuclear retaliation, thus making the United States gain an advantage in the nuclear race
On February 7, 2017, China's new year's Eve, North Korea launched a long-range rocket. On February 8, South Korea announced that it would negotiate with the United States to deploy the terminal high altitude defense system (THAAD) on the Korean Peninsula. If the anti missile system of 'Sade' finally enters the Korean Peninsula, it may mean that China is not a small geopolitical setback.
China has always been opposed to the Saad anti missile system. It is more than enough for the United States to deploy Patriot missile defense system (low altitude terminal anti missile system) in South Korea to maintain South Korea's homeland security and intercept missiles from North Korea. As a high altitude terminal anti missile system, Sade's missile against North Korea is nothing more than an ox knife for killing chickens. Its X-band radar monitoring range has reached several kilometers. Drawing a circle from Seoul, South Korea, can cover North Korea, most of Northeast China and parts of Russia's Far East. In other words, China's missile launches in its own territory can be monitored by the SARD system, thus enriching the monitoring data of the United States on Chinese missiles.
Therefore, just as foreign minister Wang Yi accused the United States of "carrying private goods": in the name of guarding against North Korea, the masad anti missile system is "Xiang Zhuang dancing the sword, intended to Peigong". Who is Peigong? Naturally, it is China and Russia. The presence of Sadr missile defense system in South Korea is a threat to China.
Therefore, once thad settled in South Korea, the United States will have a complete missile defense system in Northeast Asia: "Patriot" is a low-level terminal anti missile system; "Sade" is a high-level terminal anti missile system; and "Patriot" is a high-level terminal anti missile system; The Aegis system is a sea-based midcourse defense system. With the deployment of the midcourse defense system in the United States, the two-layer and multi-stage ballistic missile defense system built by the United States in the region has gradually formed. If we add the aegis and patriot anti missile systems that have been deployed in Japan earlier, the United States will clone the anti missile system of Eastern Europe in Northeast Asia. From then on, the strategic balance of attack and defense in this region may be completely broken, and the United States, Japan and South Korea will become the small NATO in Northeast Asia. This is a great threat to China's security environment.
If this is the case, China may have to make a worse judgment on the situation on the peninsula and make more adequate military preparations for its national security, such as increasing the number of strategic missiles and strengthening its penetration capability. The Saad system should also be included in the PLA's strategic consideration and tactical scope and make more adequate armament arrangements. If it goes on like this, it is likely to trigger a new round of arms race in Northeast Asia and make the peninsula never peaceful.
The situation on the peninsula is like a mess, and the tighter the external forces drag them, the more deadlock they will become. The crux of the problem lies with both parties: North Korea and South Korea.
For North Korea, toughness is not a long-term solution, nor sustainable. At this time, there was a lot of noise at this time. To a large extent, it was for Kim Jong Un to successfully complete the establishment of authority at the Seventh National Congress of North Korea held in May. For North Korea, what he played was a dangerous move. The more the United States and South Korea reacted strongly, the higher the prestige of Kim Jong Un in the country and the consolidation of his status. This is a political account, not an economic account. You can use economic sanctions to interfere with his political goals in a short period of time.
For South Korea, calm is the most important thing. Playing a balance between China and the United States is much more beneficial than simply turning to the United States. What's more, it's just a fantasy to let the North Korean regime collapse through the United States and South Korea's joint sanctions, and the reunification of the peninsula can not be solved by one or two crises. At present, the best way to do this is to insist on sanctions and let North Korea pay the necessary price. Second, we should not let the situation on the peninsula continue to deteriorate and drag China and Russia into an arms race. The third is to wait for the Seventh National Congress of the DPRK in May. After Kim Jong Un has consolidated his authoritative position, and limited to the limited national economic strength, North Korea's foreign policy will certainly be reduced. At that time, it should be peace talks opportunity.
