In two programmes, Gerry Northam reports on warfare and the consequences for global peace.
1: New Weapons. The Nato bombing of Serbia last year appeared to be the culmination of a strategist's dream -total victory and barely a single allied casualty.

And if so, will advanced computerised weaponry make the world a safer place?
