In August 1945, two loud noises rang out in Hiroshima and Nagasaki, Japan, which were already at the end of World War II, and the Allies did not want to delay with the Japanese army any longer, causing unnecessary casualties, so the United States dropped two atomic bombs on Japan, and exaggerated the power of the atomic bomb, shocking the world, Japan was shocked, and at noon on August 15, the Japanese emperor broadcast to all of Japan: Japan surrendered unconditionally.

Although the original atomic bomb may not have the power to destroy the earth, it is enough to shock the world, so at the end of World War II, the Soviet Union, Britain, France and other countries have developed their own atomic bombs, and compared with the "first generation" of atomic bombs, the power of future generations of nuclear weapons is naturally greater.
In 1964, China successfully exploded an atomic bomb, becoming the fifth nuclear-armed country on Earth. But the end of World War II does not mean that the smoke of war has disappeared from our country.
After World War II, chiang kai-shek provoked a civil war, the war of liberation lasted for five years, in 1949 the founding of New China, the next year the outbreak of the Korean War, when our country was still weak, in a period of waste to be revived, the five-star general of the United States believed that our country did not have the courage to participate in this war, so its behavior was more arrogant.
The US military ignored China's repeated warnings, and even its aircraft repeatedly invaded China's territorial airspace and bombed the Dandong region, and the flames of war were about to stretch to the Yalu River, and our country profoundly understood the truth of the cold lips and teeth, although at that time, our country was still relatively poor, and there were no good weapons, but it was not afraid of anything, and the Chinese People's Volunteer Army crossed the Yalu River and arrived at the Korean battlefield.
It was an extremely difficult battle, but every volunteer army gave their greatest strength, for the sake of the country, but also for their own small family, Chinese the dignity of the country, but also the soul of the Chinese soldiers, MacArthur was silent.
Initially, when the Volunteers entered the Korean Theater, both MacArthur and Truman saw no fear, and after three battles, MacArthur's "United Nations Army" had to retreat to the vicinity of the 38th Parallel.
In April 1951, MacArthur advocated attacks on our military targets in the Northeast and stated that nuclear weapons should be used if necessary. It is worth mentioning that in 1950, Rear Admiral Lalo also proposed the use of atomic bombs, and on November 30, 1950, Truman declared at a press conference that "we will take the necessary measures to deal with the military situation." ”
When asked if he "included atomic bombs," Truman replied, "Including the various weapons we have." "And said that the United States has been actively considering using it (the atomic bomb)." However, Ridgway, who took over as commander of the US Eighth Army, was opposed, saying, "We are not beasts." ”
Entering the era of modern civilization, what Western countries advocate is human rights and freedoms, and the United States openly stated that it would use the extremely harmful atomic bomb, which means that it is really intriguing, so Britain, France and other countries have issued statements strongly condemning the United States as if it intends to expand the war.
And the British chief of staff also called MacArthur, "kindly" reminding: "The Soviet Air Force will inevitably participate in the battle." At that time, the Cold War was already in progress, the United States and the Soviet Union were competing for the position of world power, and if the United States intended to expand the war, the Soviet Union would naturally make some moves.
The Soviet Union's first atomic bomb exploded successfully in 1949, and Stalin responded: "The use of nuclear weapons against China is the same as the use of nuclear weapons against the Soviet Union." So when MacArthur advocated the use of the atomic bomb, Truman hesitated and eventually did not use the atomic bomb.
