Putin ordered nuclear forces to enter a special state of combat readiness, and the outside world is worried about whether a nuclear war will break out if the situation escalates. On the 27th local time, when Russian President Vladimir Putin met with Russian Defense Minister Shoigu and chief of general staff grasimov, he said that the west not only curbed Russia economically, but also made increasingly aggressive statements by some leaders, so he ordered Russia's nuclear power to enter a special state of war preparedness. Analysts believe that under the current circumstances, Russia believes that the current strategic situation is developing in a direction unfavorable to itself. With the deterioration of the strategic situation, Russia had to try to curb the military reaction of western countries by releasing strengthened nuclear deterrence signals, so as to provide guarantee for Russia to upgrade its military operations in Ukraine.

Reuters reported on the 27th that Putin's order for nuclear forces to enter a special state of combat readiness has added a worrying new factor. The concerns of the outside world are not unreasonable. Before the outbreak of large-scale military conflict between Russia and Ukraine, a series of events such as Russian nuclear exercises and Russia and France reminding each other that they have nuclear weapons constantly pushed up the nuclear confrontation. On the first day of the Russian military's "special military operation" against Ukraine, Putin mentioned nuclear weapons in his speech. Putin said that in the military field, even after the disintegration of the Soviet Union and the loss of a large part of its potential, modern Russia is still one of the most powerful nuclear powers in the world, and has certain advantages in many aspects. The latest types of weapons. In this regard, no one should doubt that a direct attack on our country will lead to the failure and terrible consequences of any potential aggressor. On the same day, the French Foreign Minister also responded. When Putin issued such threats, he should remember that NATO is also a nuclear alliance. For Putin's move to order nuclear forces to enter a special state of war preparedness, Zhao daopeng news (www.thepaper. CN), a researcher at Tsinghua Carnegie global policy center, believes that Putin's prediction of the Counter-measures of western countries is insufficient. Western countries from economic sanctions to arms assistance to Ukraine, and then to NATO's mobilization of rapid response forces, the strength and scope of countermeasures may exceed Putin's expectations. Russia believes that the current strategic situation is developing in a direction unfavorable to itself. With the deterioration of the strategic situation, Russia had to try to curb the military reaction of western countries by releasing strengthened nuclear deterrence signals, so as to provide guarantee for Russia to upgrade its military operations in Ukraine. An arms control researcher who asked not to be named said that whether Russia's nuclear forces enter a special state of combat readiness will trigger a reciprocal response from other nuclear powers, especially NATO countries, deserves close attention. Due to the huge damage capability of nuclear weapons, all nuclear weapon states will be very cautious, and the risk of nuclear war is minimal, unless there is a "madman" on one side to use nuclear weapons in this sensitive period. It is worth mentioning that the planned strategic deterrence exercise was held on February 19. The Kremlin website announced on February 19 that Russian President Vladimir Putin and Belarusian president Lukashenko watched the exercise together. It is said that ballistic missiles and cruise missiles were launched during the exercise, and all missiles hit the designated targets. According to the information released by the Russian side, in terms of strategic nuclear forces, the participating troops launched "yars" intercontinental ballistic missiles from the Plesetsk national space test site to the Kula shooting range on the Kamchatka Peninsula. The cruise missile launched by tu-95ms strategic bomber hit the targets at pemboyi and Kula shooting ranges. The "Karelia" nuclear powered strategic submarine of the Northern Fleet launched a "blue sky" submarine launched ballistic missile at the Kula shooting range in the waters of the Barents Sea. In terms of non nuclear strategic forces, surface ships and submarines of the Northern Fleet and the Black Sea Fleet launched "caliber" cruise missiles and "zircon" hypersonic missiles at sea and land targets. In addition, the participating troops launched a land-based "Iskander" - K cruise missile from the kapskanyar shooting range in Astrakhan. In the view of the outside world, the strategic exercise serves for the "special military operation" on the 24th to show the outside world the nuclear power of the Russian army.

At present, Russia has a nuclear arsenal equal to that of the United States, and it is enough to destroy the whole world. According to the information published in the bulletin of atomic energy scientists of the United States, by the beginning of 2020, Russia had about 6370 strategic and tactical nuclear warheads, of which 1570 strategic nuclear warheads were in active deployment, and 870 strategic nuclear warheads and 1870 non strategic nuclear warheads were in storage. In addition to the military reserves for combat forces, there are about 2060 decommissioned nuclear warheads pending dismantlement (still operational). In terms of land-based nuclear forces, according to the bulletin of atomic scientists, Russia has 11 ballistic missile launchers, equipped with 302 intercontinental missiles, including SS-18, SS-19, SS-25, ss-27 and other intercontinental ballistic missiles. Among them, ss-27 series is the backbone of land-based nuclear forces, with a number of 218. The three ballistic missiles SS-18, SS-19 and SS-25, which were developed in the Soviet era, are gradually decommissioned or modernized. In terms of sea based nuclear forces, the Russian navy is equipped with 10 strategic nuclear submarines, including 6 "delta" - 4, 1 "delta" - 3 and 3 "Northwind God" class nuclear submarines. These submarines can carry 16 submarine launched ballistic missiles and are equipped with separately guided nuclear warheads. Ten submarines are equipped with about 720 nuclear warheads. The air-based nuclear force now has about 68 strategic bombers, including 50 TU-95 series and 13 Tu-160 series. These bombers can carry kh-55 and kh-102 nuclear cruise missiles, and their range of more than 2000 kilometers gives strategic bombers the ability of standoff attack. At present, Russia has begun to modernize and upgrade TU-95 and Tu-160, equipped with more advanced electronic equipment and airborne weapons, and a new generation of bombers is also being developed. Last month, Russia's first newly manufactured tu-160m strategic bomber made its first successful flight, which is of great significance for Russia to improve its air-based nuclear power. Russian Deputy Defense Minister Borisov previously told the media that in the future, the aerospace force will equip 3-4 such aircraft every year and plans to produce a total of 50 tu-160m. Russia test fired "pioneer" hypersonic missile. On June 2 last year, Russian President Vladimir Putin signed Russia's nuclear deterrence policy, and the relevant documents were published on the official website of Russian legal information. As for the status and role of nuclear weapons in Russia's military forces, the new nuclear deterrence policy points out that Russia regards nuclear weapons as a means of deterrence, which is a necessary measure in extreme cases. Russia will make all necessary efforts to reduce the nuclear threat and prevent the deterioration of inter state relations from inducing military conflicts, including nuclear conflicts. Under what circumstances will Russia retain the right to use nuclear weapons? The nuclear deterrence policy points out that first, potential opponents use nuclear weapons or other weapons of mass destruction against Russia and its allies; Second, Russia was invaded by conventional weapons, which threatened the survival of Russia. There are four specific conditions for the use of nuclear weapons: 1. Learn reliable information about ballistic missile attacks on the territory of Russia and its allies; 2. The enemy uses nuclear weapons or other weapons of mass destruction to attack the territory of Russia and its allies; 3. The enemy attacked important Russian countries or military facilities, resulting in the inability of these facilities to operate and the interruption of the response of Russian nuclear forces; 4. Russia's invasion with conventional weapons has threatened its survival. The nuclear deterrence policy stipulates that the Russian president is responsible for deciding whether to use nuclear weapons. If necessary, the president of Russia can inform the leaders of other countries or international military and political organizations of Russia's readiness to use nuclear weapons, or its decision to use nuclear weapons and relevant facts. Zhao Tong told surging news that this is the first time Russia has publicly released a more detailed nuclear deterrence policy. The main contents are consistent with other major military strategic outlines of Russia and the public policy statements of leaders. There are no major changes in nuclear strategy and no significant changes in the use of nuclear weapons. In Zhao Tong's view, Russia has also included some vague conditions in the use of nuclear weapons, such as when key civilian and military facilities are attacked, which may affect Russia's nuclear counterattack capability. "This is noteworthy. This covers a wide range, and there is also the risk of misunderstanding: for example, the enemy does not know which civil or military facilities may be related to Russia's nuclear counterattack capability, resulting in the miscalculation of the nature of the attack on both sides." Zhao Tong said. (Xinhua News Agency)
