American way of making history

America is one of the most powerful leaders in the world. they have economical power and international one at the same time. They have numerous population and huge lands. And these surrounding conditions helped America get the power. However, they also are evaluated as a high level and their culture is very influential. so American cultural power is easily shown to our Korean country. For example, their music, Hollywood films are very popular to Korea and eastern countries. American style foods are also well know to us as MacDonald, KFC, TGI Friday, and etc. above all, America has cultural comparative power in the history. Many Korean people curious about this opinion. When we comparing their history with ours, American history is absolutely shorter than Korean history. American history is only few hundreds. but Korean history is more than two thousand years. what's happening here? why korean history can't be regarded as good level as American history? From the Vietnam war, Koreans can find the reason why Amercan has historical power.
From the beginning of the Vietnam war, American didn't have any right to participate. It was a simple war between France and Vietnam. But, America participated in the war for the purpose of protecting Vietnamese from communist. At that time, there was cold-war between USSR and the U.S. so that the U.S. used "Domino theory" for making necessity of participating. America insisted that the slump of Vietnam would spark a global wave of communist triumphs. Moreover, Americans always had won other wars for example, Korean war:) before the Vietnam war. They were sure to win aganist Vietcong. Their enemy, Vietcong, already was supported by almost Vietnamese people and government people. More than worse, American troops were hard to distinguish enemy from villagers. They had to kill the civilians even though they were children. After America was defeated, they were still insited that they did right thing and instead of their guilt, Americans blamed Vietnam. For example, Ho-Chi Minh was knowan as a [person without a father] at that time. In short, dominant culture of the USA justified their reason of the war though America was defeated.
After some decades, new thoughts and voices about Vietnam war came out in the USA robert McNamura. He admitted that American imperialism made the Vietnam War more serious and it sacrificed many American young ppl and Vietnamese. Furthermore, Bob Kerry revelaed his true experiences and opinions about Vietnam War in newspapers and television screens. He said that he was very shameful about his war experiences. He described that his Navy seal killed innocent women and children while on a mission in the Mekong Delta. He aslo mentioned a story about free-fire zone where Americans were too aggressive. McNamura and Kerry's attitudes were absolutely in contradicition to dominate ideas. Nevertheless, these men bravely began to admit American unrighteous and insisted that American apologize Vietnamese for their sin. From these Kind of brave men, different idea about Vietnam war steadily was produced in American society. American thinks about the war again. This is aganist theory.
History is like a pyramid. If u see a pyramid on the side, you would think the pyramid as a triangle. But if you see it on the top, you would think the pyramid as a square. so throughout these all sort of view, you can guess the real shape of pyramid. Just as pyramid, history also needs various and different point of view to understand of get the right direction. Compare with Korea, Amerca has some ppl like Bob Kerry, and ppl who suggest different point of view aganist main ideas. Their attitude develops their own history. That's why American have high level of history even though they have short period of history.
