I'm not opposed to this at all but I question how exactly enforcement would/can work. We don't know with 100% accuracy who was responsible for Stuxnet, Flame, Operation Aurora, etc and especially with code, it is going to be exceedingly difficult in most cases to get evidence such that blame can be leveled with any certainty.

Furthermore unlike nukes it is completely impossible to verify that a country dosen't have cyber weapons. Cyber weapons can be hidden in someone's shoe, you can't do that with a nuclear arsenal.

From what we've seen, these cyberweapons take a long time to work their way behind enemy lines and must evolve as they do so. If it's hidden in a shoe then it's not really a useful cyberweapon.
