In boot camp, we were taught to hate the "G O O K's" Trained to kill the hated Vietnamese enemy, and I did the job as well as I possibly could...
A couple of years later, after the fall of Saigon, the first waves of Vietnames refugees started coming to the US. MANY ex-military couldn't separate the Vietnamese we were trained to kill from those who were leaving because of the Communist take over...Once I left Vietnam, I put that bullshit behind me. You just can't go through life hating everyone because they're different than you.
FYI, Wikipedia sez:
*****
(U.S. military slang) an Asian person, especially an enemy (e.g. Koreans or Vietnamese during the Korean and Vietnam wars). By extension, any Asian person. Derived from the Korean words ?hanguk? and ?miguk?. Guk is from the Chinese word guo, which means country. ?Hanguk? refers to Korea[25] and ?miguk? is the common word for the United States.[26] American troops thought "miguk" sounded like "me *****" (i.e. "I am a *****"). The word persisted during the Vietnam War, perhaps also because the Vietnamese people have a similar word ?qu?c?, meaning "country". "*****" was also used by white soldiers in Africa to designate enemy insurgents.
