I have read the book you refer to. "The Third World War" written by General Sir John Hackett, published by Macmillan in 1985. It was published in two versions as the original was originally manuscript was written when the Shah was in power in Iran. The second or modified version reflected the realities imposed by the Sha's downfall.

It has been some time since I read it, but I cannot recall any resort, on the part of NATO to use CB weapons. When I get the chance I will go back and check.
