I watched the 1975 Vietnamese evacuation up close while assigned to Hickam AFB, Hawaii. They arrived with either a suitcase or a sack. The first generation got on their feet. The second generation is mainstream American. There were no programs or sympathy for them. They just took care of business. I would ask this Dalton diversity crowd why they think the Vietnamese succeeded. I would expect them to change the subject.
I worked with a man who escaped from Vietnam as a teenager on a boat. We spoke at length about what the communists did there.
