It has not done what for instance the Americans did in Vietnam... it did not use napalm, it did not kill millions of peopleThis is a patently false statement (and a vicious canard) worthy of Ted Turner or Mrs. Ted Turner. Millions of innocents did die in Viet Nam, but only after the US withdrew and the NVA conquered the South.
If professor Van Creveld's brain is full of such misinformation then it would be best to ignore him.
No "if" about it. Remember Viet Nam is 30 years ago. He wass just a student then, and absorbed the conventional wisdom of the academy.
