When an American soldier in Vietnam killed a superior officer, the term “fragging” came into use. Although the term simply meant that a fragmentation grenade was used in the murder, it later became an all-encompassing term for such actions. Hundreds or thousands of “fraggings” occurred during Vietnam, but the precise number is uncertain.
Anarchy in the age of dinosaurs
It happened because the USA sided with the so called Communist USSR instead of Germany during world war 2 enabling Vietnam to be taken over by communists
If USA sided with Germany and defeated the so called communists then so called communists would not have taken power in Vietnam
Possibly unless Germany and the USSR were actually both controlled by the same people or sentient beings
