Don, I am familiar in concept with what you are saying but a book that was written centuries before I was born can't know what will happen to be specifically. I will buy that given the cyclic nature of history that the future can somewhat be predicted. The USA became involved with a way at almost predictable intervals, which some allege was an economic plan. The war machine creates jobs for soldiers and industries supporting soldiers and when the economy started to sag, the country went to war. WWII to Korea, Korea to Vietnam, Vietnam to the Gulf....

Imagine being a soldier with that power. If you know you are going to be killed tomorrow, how likely are you to go into that battle knowing how it ends? That leads to a bigger issue of how someone might be able to change history if they know the future.
