Final answer:
American veterans of the Vietnam war were not recognized and honored for their service and sacrifices until many years after the war ended. It was not until the 1980s and 1990s that the attitude towards Vietnam veterans started to change.
Step-by-step explanation:
Veterans of the Vietnam war were not recognized and honored for their service and sacrifices until many years after the war ended. When these veterans returned home, they faced a nation that was divided on the war and many Americans were against it. As a result, they did not receive the same level of recognition and appreciation as veterans of previous wars, such as World War II.
In fact, it was not until the 1980s and 1990s that the attitude towards Vietnam veterans started to change. The creation of organizations like the Vietnam Veterans Against the War and the efforts of veterans themselves helped raise awareness about their experiences and the challenges they faced when they returned home. Eventually, the public began to recognize and honor the sacrifices made by these veterans.
