Science fiction invites the writer to grandly explore alternative worlds and pose questions about meaning and destiny.

There are many different rivers that lead into despair: there's poverty; there's political repression; there's gender apartheid - there's a sense of culture loss; there's religious fanaticism.

We've been sending billions and billions of dollars to Israel and Egypt for decades to keep the peace. So as an American taxpayer, I have an interest in this. It's galling to feel that as an American I have a higher stake, a higher interest in peace than you do.

If we're talking about Sinai, we can't understand it without the 1967 and 1973 wars, and you can't understand it without the biblical story of Moses leading his people through the wilderness.
