The first time the United States used atomic bombs in war, it was also the first time in human history that nuclear weapons were used in actual combat, which shocked the governments of the world visually and spiritually. It makes people think that one or two atomic bombs can determine the direction of a war.
The United States was the first country in the world to possess an atomic bomb, and the United States was bent on dominating the world. The atomic bomb naturally became an important weight for the United States to threaten the rest of the world. At this point, as long as the United States and any country "do not agree with each other", they will take the atomic bomb out and threaten the country to submit to its own will. The term "nuclear monopoly, nuclear threat" was born.
In the Korean War, the United Nations army led by the United States was defeated by the Chinese army. The United States had to repeat the same tactics and take the atomic bomb out to talk about it, in an attempt to threaten China and make China retreat to North Korea.
At a press conference, U.S. President Harry S. Truman discussed the atomic bomb.
Anthony Levero, New York Times reporter: Mr. President, does the attack on "Manchuria" depend on the actions of the United Nations?
Truman: Yes, exactly.
ANTONI LEVERO: In other words, if the United Nations authorized General MacArthur to go further, would he do it?
Truman: We will take whatever steps are necessary to meet the needs of the military situation, as we often do.
New York Daily News correspondent Jack Doherty: Does that include the use of atomic bombs?
Truman: That includes any weapons that we have.
Chicago Daily News reporter Paul Leach: Mr. President, when you say "any weapon we have," does that mean that the use of an atomic bomb is being actively considered?
Truman: The use of atomic bombs has been actively considered. I don't want to see it used. This is a terrible weapon that should not be used against innocent men, women and children who have nothing to do with this military incursion. And that would happen if an atomic bomb were used.
This time, however, Truman was looking for the wrong target of the threat. Truman's speech at the press conference was quickly disseminated to Beijing. The news that the United States will use atomic bombs in the Korean War caused an uproar at the top of the Chinese hierarchy, but Mao Zedong, chairman of the Central Military Commission, was not intimidated by Truman, still believing that the atomic bomb was a paper tiger and could not determine the direction of the Korean War, and the possibility of the United States using the atomic bomb this time was zero. Indeed, so is the truth.
Similarly, Truman's speech also caused an uproar in the British Parliament, with some 100 British Labour MPs jointly proposing to Prime Minister Clement Attlee against the use of the atomic bomb under any circumstances.
At the same time, ambassadors from various Western countries rushed to Austin, the U.S. ambassador to the United Nations, to raise the concerns that Truman's speech on the use of the atomic bomb had caused them. Various countries have expressed their firm opposition to the re-use of atomic bombs on the battlefield. At this point, the United States coalition camp at the United Nations quickly collapsed.
Soon after, Chinese representatives arrived at the United Nations headquarters, and under the "nuclear threat" on the Part of the United States, China's attitude remained uncompromising. The U.S. "nuclear threat" against China ended in failure.
After the United States, the Soviet Union's first atomic bomb was successfully tested in 1949, becoming the second country in the world to possess nuclear weapons. Due to the continuous increase in the number of nuclear-weapon countries in the world and the changes in the international situation, China decided to develop its own atomic bomb. Due to the limitations of the field of scientific research and development, China, as a socialist country, hopes to be able to get the help of the Big Brother of the Soviet Union.
The Soviet Union also had its own plans, that is, the fewer nuclear-weapon states in the world, the greater the deterrent power of nuclear weapons. So fundamentally, the Soviet Union did not want China to be able to develop an atomic bomb, which in turn would put China under the Soviet Union's "nuclear umbrella." This is also a disguised "nuclear threat" to China.
The atomic bomb is a paper tiger, we should despise it strategically, but we must pay attention to it tactically, if we do not have our own atomic bomb, sooner or later the paper tiger of the atomic bomb will also become a real tiger.
After arduous discussions between the Chinese and Soviet sides and after agreeing to various unreasonable conditions of the Soviet Union, the Soviet Union reluctantly agreed to help China develop the atomic bomb. Atomic bomb experts were sent to China by the Soviet Union, but in the process of development, the core information was still not handed over to the Chinese developers. It didn't take long for the Soviets to withdraw Chinese Soviet experts for various reasons and to take with them all the information about the atomic bomb.
Under the rapid changes in the international situation and the dark clouds of "nuclear threat" all over the world, China decided to take the road of developing atomic bombs alone and break the "nuclear threat" of nuclear-armed countries to China.
On January 15, 1955, Mao Zedong presided over an enlarged meeting of the Secretariat of the Central Committee of the Communist Party of China, at which the strategic weapons were discussed and decided.
In 1958, the Central Military Commission of the Communist Party of China proposed the "Guidelines for the Development of Nuclear Weapons" for the National Defense Science Commission.
At 15:00 on October 16, 1964, China's first atomic bomb was successfully exploded in Lop Nur in Xinjiang, making China the fifth country in the world to possess nuclear weapons.
So far, China has shaken off the dark cloud of "nuclear threat" and "nuclear monopoly" of the world's nuclear countries.
