Query: The Moon as the Persian Gulf of the 21st Century

One of the last men to have walked on the Moon has written a great book on why the next people should visit the Moon and eventually stay. Dr. Schmitt's premise is that a substance called Helium 3, found in some quantity mixed with lunar soil, can be the fuel for fusion reactors of the future. If he is right, then the Moon might just be the Persian Gulf of this century, providing a great deal of the world's energy needs. Thus, Return to the Moon is a topical book in light of President Bush's initiative to return humans to the Moon. A must read for anyone interested in the future.
