Actually, I'm in agreement that a cyber attack could be very bad, potentially as bad or worse than a physical attack. However, proving who was responsible may be impossible (to the burden of proof necessary to justify a military response.)
> The lack of civilized behavior which speaks from your notion of "every country for themselves" is appalling.
Whether you agree or disagree, countries spying on each other has been around since antiquity. Is it "right"? That really does depend on which side you're on. The British breaking Enigma and reading Nazi codes was almost certainly "right", unless you were a member of the German Navy and your U-Boat was sunk, in which case it was cheating?
Was China's (presumed) hacking of US companies for economic espionage "right"? We in the US see it as cheating (stealing intellectual property), I'm sure China has a justification that they see as completely valid.
If I can make a completely sarcasm free recommendation, look up the ethical theory of Cultural Relativism.
