As for the reasons for the War to Resist US Aggression and Aid Korea, it is actually not as simple as imagined.
The current mainstream understanding is that the War to Resist US Aggression and Aid Korea was a war of national founding fought by New China in order to resist US aggression, but in fact, behind this war is a complex game between China, the United States, the Soviet Union, and the DPRK.
Chairman Mao has been to the Soviet Union twice in his lifetime, once from December 6, 1949 to February 17, 1950, and once in November 1957.
At that time, New China had just been founded, Tibet had not yet been liberated, there were still many remnants of the Kuomintang on the southeast coast, bandits in the southwest region were piled up, and the whole country was still in a state of devastation; to tell the truth, the common people at that time wanted to have a peaceful birthday in two days, no one wanted to continue to fight, and Chairman Mao did not want to fight any more, so two months after the founding of New China, he rushed to the Soviet Union, the purpose was to abolish the unequal "Old Sino-Soviet Covenant", and then carry out economic cooperation with the Soviet Union to help restore production at home.
Therefore, Chairman Mao still attached great importance to this trip, and when he heard that Stalin's 70th birthday was approaching, he prepared gifts such as the statue of Marshal Stalin, an ivory dragon boat, Shandong green onions, and Jiangxi honey oranges, which not only appeared honorable, but also used crops to narrow the distance with Stalin.
But at that time, the Attitude of the Soviet Union toward Chairman Mao was not very friendly, for three reasons:
First, Stalin knew that Chairman Mao was on the verge of abrogating the treaty, and he was not happy in his heart.
Second, the Soviet top brass did not recognize China's strength at the time, but only treated it as an ordinary friend.
Third, the founding of New China broke the strategic layout of the Soviet Union in the Far East.
Therefore, when Stalin heard that Chairman Mao wanted to abolish the "Sino-Soviet Old Testament," he was unhappy in his heart and found various reasons to shirk it; in order to stabilize Chairman Mao, Stalin dragged Chairman Mao to visit the factory every day, and let Chairman Mao watch biographical films of Historical Figures in Europe.
Chairman Mao, of course, would not give up, and he held a second meeting with Stalin, but he did not expect that Stalin still did not talk about the treaty, and even began to close the door directly; this attitude made Chairman Mao very angry, so he made a decision -- to publicize the news of the establishment of diplomatic relations between New China and all countries in the world.
The purpose of this is to stimulate Stalin and make Stalin understand that if you do not face up to your relations with New China, we can also cooperate with other countries, and then you will regret it too late.
Moreover, at this time, the British media found that Chairman Mao had been unheard of for a long time after he went to Moscow, so they did not think that it was a big deal to speak to the outside world: Mao Zedong was under house arrest by Stalin.
As soon as this news came out, it was like a bombshell that exploded in the international community, and you think, as the big brother of a socialist country, he actually put the leaders of friendly countries who went to your country for talks to put them under house arrest, so who would dare to cooperate with your Soviet Union after that? Can this team still be brought?
So Stalin was so frightened that he quickly stood up to refute the rumors, announced chairman Mao's itinerary, and was forced to agree to a new treaty with China to replace the unequal old treaty.
The reason why Stalin insisted so much on the "Sino-Soviet Old Testament" was because Chiang Kai-shek promised the Soviet Union that Lushun would be a shared naval base between the two countries, and Dalian would be a free port, that is to say, the Soviet Union had the right to garrison troops in Chinese ports, which was of great significance to the Soviet Navy that did not have an ice-free port, after all, if the port was frozen, it meant that the aircraft carrier could not go out, which meant that the Soviet Navy could not maintain strong combat effectiveness for a few months a year. From Catherine to Stalin to today's Putin, what they have in mind is to get a freeze-free port in the whole world, and it is hard to have the naval base of Lushun, and now they have been ordered by Chairman Mao to go back.
Therefore, on January 30, 1950, Stalin, while negotiating a new treaty with China, telegraphed Kim Il Sung to quickly expand his army and prepare for war.
On February 17, Chairman Mao left Moscow, and a Stalin-led conspiracy began to be carried out in secret.
From April 10 to 25, Stalin secretly met with Kim Il Sung and agreed to North Korea's plan to start a war and prepare to build a Soviet naval base on the Korean Peninsula in the future.
In May, Kim Il Sung went to Beijing and proposed his plan to Chairman Mao, who opposed it.
On June 25, without informing China, North Korea suddenly went to war.
On June 26, the United States began to intervene in the Korean theater.
On June 27, the U.S. Seventh Fleet entered the Taiwan Strait to prevent China from liberating Taiwan.
On October 8, the Korean People's Army was defeated and retreated, and the Chinese Volunteer Army crossed the Yalu River.
This is an important timeline of the causes of the incident to resist US aggression and aid Korea.
Next, I will analyze what the four sides of the United States, the United States, the Soviet Union, and the DPRK are thinking.
For the Soviet Union, it was a game that could hardly be lost.
In the first case, if North Korea defeats South Korea and the United States does not send troops, then the Korean Peninsula is completed, and the Soviet Union successfully obtains the ice-free port in the south of the Korean Peninsula.
In the second case, if the United States sends troops to defeat North Korea and troops on the Chinese border, then the Soviet Union can send troops to the northeast to protect the Middle and Long Railway in accordance with the Sino-Soviet Friendship Treaty, so that the garrison will become a fact, and then go to the United Nations to put pressure on the United States to return to the 38th Line.
In the third case, the United States defeated North Korea and China sent troops, but China could not defeat the United States and was forced to ask the Soviet Union for military assistance, and the Soviet Union could also make the garrison a fact.
Therefore, when the Soviet Union held a meeting at the United Nations to discuss the Korean Peninsula issue, it directly gave up its veto power and chose to abstain and be absent, because it was very clear that the Korean Peninsula was China's buffer, but it was not its buffer, and Northeast China was its buffer, so in fact, The DPRK did not lose its heart and did not care so much.
For the United States, if the Korean Peninsula is reunified, then the wave of communism will directly approach Japan, which is not conducive to the layout of the United States in the Far East, and if the Soviet Union is allowed to expand its sphere of influence on the Korean Peninsula, it may prompt the Soviet Union to continue to take risks in the Middle East and Europe, so it is necessary to stifle the Soviet Union's ambitions in the cradle, plus Truman was facing a lot of pressure at home at that time, he urgently needed a war to divert the contradictions, and more importantly, the United States believed that China would never come to this muddy water.
For North Korea, the opportunity to reunify the peninsula may be only once, even if it knows that it is shot by the Soviet Union, it must be on the front line, otherwise it will lose this opportunity, and under the game of China, the Soviet Union and the United States, he may never have a similar opportunity.
For China.
If we do not fight, we will face long-term military pressure from the United States, the northeast will become a front line of confrontation, and long-term military expenditures will seriously drag down economic construction. Fighting will increase the economic burden, be used as a gun by the Soviet Union, and once the war cannot be won, the Soviet Union will intervene and will continue to be under the military control of the Soviet Union.
It can be said that no matter how you choose, it is not a good way out.
However, it was in this desperate situation that Chairman Mao miraculously broke the situation.
The Americans used all advanced weapons except the atomic bomb, and they could not move a single bit in front of the 38th Line, Chinese used their own strength to fight a peaceful environment for more than ten years, and also won the respect of the Soviet Union and the industrial assistance of the Soviet Union.
Looking back on Chairman Mao's life, he simply possessed supernatural judgment ability; the War of Resistance Against Japan was in a hurry, the War of Liberation could not be delayed, and the Korean War could not be retreated!
Chairman Mao has not miscalculated in the three wars concerning China's national fortunes.
After reading the real reasons for the War to Resist US Aggression and Aid Korea, you can only know how amazing Chairman Mao is
