War, as we all know, is often accompanied by the use of weapons of mass destruction, which brings huge losses to the theater of operations. World War II is a stark example, with more than 70 million deaths and $5 trillion in economic losses. With the continuous advancement of science and technology, soldiers' weapons have gradually evolved from cold weapons to more destructive hot weapons, such as guns, shells, tanks, fighters, warships, etc. In recent years, the types of weapons have been increasing, their performance has become more advanced, and their lethality has been continuously improved. But there are some weapons that have been banned by the international community because of their cruelty and costly use, such as the frightening nuclear weapons.
However, in the Vietnam War, despite the strong opposition of the international community and China and the Soviet Union, the United States used a banned weapon, the "rain bomb", which caused flooding in Vietnam for six months, killing tens of thousands of people, including American soldiers. The Vietnam War was one of the most expensive, longest, and most costly wars in the United States since World War II. However, although the United States dropped more ammunition in the war than World War II, up to 15 million tons, it did not achieve a clear advantage. Due to the complex terrain and the Vietnamese's expertise in guerrilla warfare, the U.S. forces retreated and suffered heavy losses.
In desperation, the U.S. military decided to use "rain gas bombs" to attack the Vietnamese army. This shell is not used to kill, but by adding some chemical powder to the shell, causing it to explode when fired, resulting in a series of collisions that eventually cause rain to fall. Typically, countries only use this technique during prolonged droughts. The U.S. military dropped 4.74 million "rain gas bombs" in one go, which, combined with Vietnam's already rainy climate, led to large-scale flooding that lasted for six months. The man-made floods destroyed countless roads, bridges, crops and buildings, displaced Vietnamese people and killed tens of thousands.
This act was condemned by the international community, including strong opposition from China and the Soviet Union. However, the United States, by virtue of its world hegemony, is determined to go its own way. However, this move not only failed to bring a decisive victory, but also caused his troops huge losses and became self-defeating. In addition, the U.S. military used other chemical weapons in the Vietnam War, such as Agent Orange and defoliant, as well as the use of "empty pregnancy galactagogues" on female prisoners, which are undoubtedly immoral and cause lifelong damage to the victims.
The war was the most shameful of any war in which the United States was involved, causing huge losses, not only more than $200 billion economically, but also economic recession and escalating domestic tensions. The long war also brought psychological trauma to the US military participating in the war, and 80,000 US troops committed suicide after the war, all of which can be said to be self-defeating.
