Let's say 'within profitable levels'.
Not all weapons are that good for enabling an army to advance, even if lots of people are killed, e.g. poison gas. Civilians get instantly killed by the stuff but armies are tooled up to survive it, or can be. With not much profit in poison gas compared to a cruise missile laced with depleted uranium it makes sense to ban the poison gas that anyone with a degree in chemistry can make in their front room rather than the missile.
Instead of cyber war being the threat those conventional and nuclear weapons are the threat, although hard to imagine if living in Kansas.
What we need are some jolly clever OSS licenses that have clauses in them 'not for military use'. Microsoft could put that in their license today and go heavy on the enforcement - 'sorry Lockheed Martin you can't be using Excel to design 'echelon 2 as that is in violation of the EULA, here is the cease and desist...'.
In this way we can make the military contractors fall out of the loop and be as IT savvy as North Korea.
'Don't be evil' is something we forgot about, however, again, if Google just 404'd on the military due to some EULA then that we wouldn't have so much evil in the world.
Seems that 'cyber terror' is the new al-qaeda, i.e. make believe.
