On more than one occasion, I, like Martin Sheen in "Apocalypse Now," took my patrol boat into Cambodia

In fact, I remember spending Christmas Day of 1968 five miles across the Cambodian border being shot at by our South Vietnamese Allies who were drunk and celebrating Christmas. The absurdity of almost being killed by our own allies in a country in which President Nixon claimed there were no American troops was very real. But nowhere in "Apocalypse Now" did I sense that kind of absurdity.
