Not everyone supported the troops during the Vietnam era, as a matter of fact a lot of people despised them. Some holding office now ^cough* John Kerry *cough*. But there were some patriots at the time that supported the troops through thick and thin. Bob Hope was one and he made sure that he brought a little bit of home to the troops every Christmas.
Even though it wasn't a popular war, Bob Hope didn't let that stop him from showing how much he cared for the men and women who sacrificed their lives and time away from their families to serve their country.
Bob Hope and his USO ensamble were real patriots.
