In the 10th century AD, when our country entered the Period of the Five Dynasties and Ten Kingdoms, when our country was in a situation of fragmentation, Vietnam was freed from our control. After the establishment of the Yuan Dynasty in China, Vietnam repeatedly repelled the attacks of the Yuan army, and finally sent emissaries to reconcile with our country. After that, Vietnam sent emissaries to our country to request that the name of the country be changed to South Vietnam, and finally the Jiaqing Emperor of our country gave the country name Vietnam.
In 1940, the Japanese fascists invaded Vietnam, and the Vietnamese people began to resist the Japanese invaders, and finally won the victory. After the end of World War II, Japanese fascists were expelled from Vietnam and Vietnam declared its independence. Unexpectedly, in just a few months, France invaded Vietnam again, and Vietnam carried out a 9-year war of resistance against France.
In 1961, the Vietnam War broke out, and the United States formed a coalition with South Korea, Thailand and other countries to intervene in the war. It is understood that the reason why the United States intervened in this war was because at that time, our country and the Soviet Union formed an alliance, which posed a huge threat to the United States, and the United States had no choice but to support Japan. At that time, Vietnam was the pillar of Southeast Asia, and if Vietnam developed rapidly, Japan's security would definitely be seriously threatened, which is why it was necessary to interfere in Vietnam.
As we all know, after the end of World War II, the United States went to the path of hegemonism and participated in nearly 200 wars of all sizes. These wars have more or less brought benefits to the United States, which has almost always been a victor in the war. But this war alone, the longest in U.S. history, cost nearly $250 billion, something the United States never expected.
It is said that the geographical location of Vietnam at that time was more complicated, and Vietnam had the support of our country and the Soviet Union, which extended the duration of this war. The US military was defeated and retreated, and in desperation, it dropped 4 million rain bombs on Vietnam, resulting in tens of thousands of people in Vietnam being swallowed up by floods and suffering heavy casualties. Of course, the U.S. military also learned a bitter lesson in this war and decided that until the end of the Cold War era, it would never use large-scale ground forces to carry out a traditional protracted war of attrition.
This is also the reason why the United States later turned to huge air and sea operations, because the US military knows that the sea and air superiority and technical superiority can be fought quickly and quickly, and the losses are small. In addition, this war brought about important changes in Sino-US relations, you know, the Vietnam War deepened the ongoing confrontation between China and the United States, but after the end of the Vietnam War, in order to solve the Vietnam problem, Sino-US relations were improved.
In this war, the United States did not gain benefits, but instead entered a phase of secular stagnation. And Vietnam also suffered heavy losses because of this war, especially the harm of rain gas, which plunged the Vietnamese people into a quagmire. Before the United States did this, China and Russia actually discouraged it, but the United States ignored the warning.
