In science fiction there is a specific category of books called alternate history where you simply travel into the past and suddenly change history. What if you could travel to 1754 just before the French and Indian War in America with a modern army of the future, and decided to build a new world order? Would you stop the Seven Years' War that started in 1756? Where would you begin, how would you go about it?
These could sound like strange questions but this is precisely what many science fiction authors must deal with, they have to think of ways of changing history for the better. Like stopping wars through wars or demonstration of power in order to build a new world order. I am writing such a novel right now and it is not as easy as that. Because suddenly my small town in Quebec from the year 2039 is sent to 1754, becoming instantly the most fearsome power in the world (don't worry, Celine Dion remained safely in 2039, she was in Las Vegas when it happened).
The idea is to find a way to end all wars and occupations, if only we could put an end to all exploitation, slavery and injustices against human rights. Eliminating poverty, starvation, pollution, global warming, the list is endless. It makes you think about what could be done in the present to achieve just the same results for the future, if somehow a real superpower was actually keen on achieving these goals. History proves that such a superpower will never exist, since its self-interests and the self-interests of its main constituents always take over, take over the world.
In a way this is what today's superpowers are playing at, unfortunately this is no science fiction. Re-arranging and eliminating the world's frontiers to permit an opened international commerce which translates into exploitation. Trying to stop wars in the Middle-East through more wars that only make things worse, because our intentions are not exactly honorable.
