About American flag
Certain flags are always displayed in martial art schools, primarily the South Korean flag and the flag of the country in which the school is located.
Flags are an important part of countries around the world. They have been potent emblems of national pride, political parties, and revolutionary movements. Canadians debated for several decades whether the nation should have a distinctive flag, and, if so, what its design should be. The debate subsided somewhat after the present national flag was adopted in 1965. A similar discussion took place in South Africa in the 1920s. In South Vietnam in the early 1960s, the refusal of President Ngo Dinh Diem to allow the display of Buddhist flags was a political decision that contributed to his overthrow and assassination. The potential for expressing deep-felt emotions in a condensed, but obvious form, and with great public visibility, has made flags an important medium of political communication in the 20th century.
