The new film "Virtual JFK" is marketed as the story of the Vietnam War had John F. Kennedy not been killed. I expected a fantasy account of what might have been, and this led me to expect the following problem with the story: If Kennedy was killed because he would not fight a war in Vietnam, then supposing him to have survived Dallas would simply have left him in danger of assassination at each ongoing instant in the drama. We would have had to constantly fantasize Kennedy back to life through the course of such a movie.
