I'm almost finished with a fascinating book about South Korea. The Koreans have a word called "jeong" that doesn't have an English equivalent. But its basically a feeling or energy that exists between people or between a person and a place. A feeling of extreme loyalty in a sense that goes beyond love and more toward devotion.
In the time during the Japanese occupation, Koreans had a widespread reputation for being slothful and lazy. When they achieved independence from Japan, that feeling of jeong really went into hyperdrive as the country banded together. When a strong Christian influence intermixed with the pre-existing Buddhist and Confucian traditions, it sparked a nationwide obsession to better themselves as a country and to be the best. When a Korean raises a fist and says the English word "fighting!", they aren't just saying cheer up or hang in there. It is actually more drawing upon the embattled history of South Korea and a reminder that they owe it not just to themselves to do their best, but they owe it to their country. Maybe JFK touched upon this kind of thing briefly when he exhorted Americans to "Ask not what your country can do for you. Ask what you can do for your country."
There are stories of Americans (and other nationalities) visiting Korea and losing something like a wallet, and then being astonished when a Korean found it and went to great lengths to track down the owner and return it to them. Americans think it is amazing politeness, but it is actually rooted in jeong.
