As Mr. Reynolds points out:
Here are the money quotes by Mr. Simon:
For some reason, among the many stories, a subchapter entitled "Christmas in 'Cambodia' - Vietnam, December 1968" struck a special chord with me. Apparently, on the floor of the US Senate in 1986, Kerry asserted he was ordered into Cambodia in Christmas 1968. As he later told the Boston Herald, "I remember spending Christmas of 1968 five miles across the Cambodian border being shot by our South Vietnamese allies who were drunk and celebrating Christmas. The absurdity of almost being killed by our own allies in a country which President Nixon claimed there were no American troops was very real."
Never mind that Nixon was not yet president at Christmas of 1968, a whole slew of people, quoted in the chapter say it was impossible for Kerry to have been within fifty miles of Cambodia. They also say where he was and what he did. (It wasn't pretty.) Are they lying? Well, consider this. Despite having been repeated by Kerry many times over the years, this story (according to the chapter) is curiously absent from the Senator's recent laudatory campaign bio Tour of Duty. Why, if it was so important to him, so meaningful?
