This new micro-computer drone stuff may be -- in the right hands, with the right plans --- the remedy: by making weapons more precise in targeting, more discriminating in terms of shielding noncombatants, and more effective in obliterating the most important enemy military assets.
It seems to me that nothing was more indiscriminate that siege-warfare such as practiced against Jericho, Jerusalem, or any one of a thousand other places in the two millennia, say, between 600 BC and 1400 AD --- well before the advent of modern weapons of mass destruction. Starvation is a WMD. The subsequent cholera, typhoid and dysentery upon the weakened populations, are WMD. As are the finale, the coming of the siege engines and the tireless, merciless swords.
Surely it is more morally acceptable to go after identified enemy Mujahiddin armed to kill, than against the combatant's habibi and his baby. Antiseptic drone warfare? The more antiseptic, the better.
