1.) Is a cyber attack on US governmental or military targets by another country or tacit support from that country's government constitute an act of war? Even if the cyber attack failed? (For example, a n attack on critical military infrastructure)
I think it would depend on the severity of the attack, and whether or not it actually was an attack and not just an attempt at espionage. A cyber attack must be considered just as serious as a physical attack in that it can potentially cause a corresponding amount of damage.
For the purpose of this debate, I'd like to clarify that I mean an actual "cyber attack" rather than espionage.
Obviously this still brings up further issues:
The first would be that a cyber attack can fail or be blocked by our defensive measures and cause no damage. A physical attack, while possibly ineffective, doesn't really "fail" in the same sense that a cyber attack might. A missile can miss it's target but whoever fired at us is still going to face repercussions. But while a cyber attack might "fail" it's still an attack.
The other thing I think we need to discuss is if the extent of the cyber attack matters. I believe given a military attack on US soil, some would say "an attack is an attack" whether it killed 3,000 people or 30,000 people. Does this same logic translate to the cyber world? If some country managed to knock out our communication satellites via a cyber attack, no one is directly killed and it's possible the US public might not demand action. However, if somehow a cyber attack was pulled off that caused US civilian or military casualties, I think that the American public would demand some sort of action be taken.
These are some of the tricky nuances that keep me continuously thinking about this topic. I guess I should've also asked:
Where do you draw the line between a cyber attack that should result in military action and one that does not." But that's not an "official" question to debate
