As we all know, the Second World War caused many, large and small effects on many countries, and Britain directly lost its hegemonic position in this great war. The United States made a windfall by selling a large amount of arms in the early stage, and the overall strength of the country was qualitatively improved. In the late stages of World War II, two atomic bombs were dropped on Japanese soil during the war with Japan, causing Japan to surrender unconditionally.
The great military might of the United States was evident at this time, and after the war it became a country that could stand shoulder to shoulder with the Soviet Union. However, a mountain can not tolerate two tigers, in order to compete for the world hegemony, after World War II, the Soviet Union and the United States engaged in a decades-long Cold War, and finally the Soviet Union collapsed and failed. Since then, the United States has become the only superpower in the world today.
During the Cold War between the United States and the Soviet Union, one of the battles that had to be said was the Vietnam War, which was an important local war during the Cold War, which was huge in scale and time-consuming, and almost pulled the United States across. In 1955, South Vietnam, supported by the United States, and North Vietnam, supported by the Soviet Union, began a major war, from the initial internal war between South Vietnam and North Vietnam, to the intervention of the United States and the intervention of China and the Soviet Union, which lasted for 20 years.
In the early days of the war, the United States wanted to rely on advanced weapons and equipment, hundreds of millions of tons of artillery shells, follow the example of Germany in World War II, carry out blitzkrieg warfare, and end the battle in the shortest possible time, so it invested a lot of troops, armed equipment and ammunition, more than in World War II. But what the United States did not expect was that Vietnam's geographical environment was complex, advanced equipment such as fighters and tanks could not play a big role at all, and Vietnam, where all the people were soldiers, even women also came to the front line to fight, thus evolving into a protracted war.
It is worth mentioning that the US military in the Vietnam War, the use of extremely cruel means against Vietnamese female soldiers, the use of a drug called "empty pregnancy prolactin", the use of this medicine will become very excited, have a very adverse impact on the body and mind, the US military wants to use this method to break the fighting spirit of Vietnamese female soldiers, after the double torture of the spirit and body, let the unconscious Vietnamese female soldiers say what they know.
After the devastated Vietnamese female soldiers woke up, they basically chose to commit suicide in shame, and such an act by the United States undoubtedly belongs to the abuse of prisoners of war, and the mistreatment of prisoners of war is not allowed in the Geneva Convention. This shows the shameful and despicable aspects of the United States. If the drug is to destroy people's physical and mental defenses, then in the late Vietnam War, the United States also dropped the carcinogenic agent "Agent Orange" before withdrawing from the battlefield.
The drug was so toxic that it even affected the unborn child, causing the child to deform after birth, which also caused some combatants in the US army to be infected with the virus. After the Vietnam War, tens of thousands of American troops committed suicide due to guilt or mental stress.
