I know many and I have nothing bad to say about any of them.
A good friend's long time girlfriend came to the US from Vietnam as a young child with her parents.
She went on to get a college degree and a good job with Volkswagen. Put her son thru college and he's now an executive producer with the Discovery Channel.......
Back in 2003 I went on a ski trip with my nephew and some of his fellow medical school buddies. One of them, Vu, his parents were doctors who fled Vietnam and were relocated to North Dakota by being sponsored by a church group there......
Oz, a friend of mine, was a West Point graduate and Vietnam veteran familiar with most of East Asia. He admired the energy and hard work of Koreans but found them hard to like, yet liked the Vietnamese for their resilience and dedication to friends and family.
