"Back home, the United States is engaged in another kind of war. It's a battle over segregation. In 1964, President Kennedy's successor, Lyndon B. Johnson, signed into law the Civil Rights Act, which ended segregation in public places and prohibited discrimination on the basis of race, color, religion, sex, or national origin. Not everyone is happy about it. Some white people cross to the other side of the street when they see me. Some white soldiers I know, too."
