Future War

In the future when wars are fought by robots, do you suppose they'll be able to extrapolate the winner beforehand and thus make warfare unnecessary?

Forget the robots. Wars should be decided by coin toss.

There was a Star Trek episode called 'A Taste of Armageddon' where two warring planets populations fought wars by computer simulation and voluntarily victims were stepping into disintegration chambers, effectively commiting suicide to keep acconts with the virtual computer war simulations statistical results.
