I did a simple check by asking the common Vietnamese about the Vietnamese in Cambodia and none of them so far know of or heard of any friend, neighbor, relative who settled in Cambodia.So, how did 1 million Vietnamese out of 50 million managed to leave Vietnam to settle in Cambodia without anyone else in Vietnam (the other 49 million left in Vietnam) to know anything about it?I only talked to a couple hundred Vietnamese and all of them did not know anything about the resettlement. So statistically it is impossible for such a big movement to escape any attention.I tutored a couple dozen Khmer students in High School and College and all of them were so dumb. I am not saying all Khmers are dumb. I merely said all Khmer students I met so far are so dumb, so statistically, chance is the Khmer race is very dumb. Last I checked, the Khmer math team ranked 105th out of 111 countries in the International Math Olympiad while the Vietnamese team ranked third in the world.Clearly the statistic indicates that Vietnamese are vastly superior than the Khmer. Agree?
