I think this was what I was alluding to in my prepared remarks.
Professor Lackenbauer explained very well the difference between denial and retaliation. The question is why. Why is it necessary to have that denial to thwart it? After all, why isn't the threat of punishment enough?
I think it comes down to what an adversary might think they can get away with beneath the perceived threshold of that big reprisal, of that big punishment, especially a nuclear reprisal. If an adversary thinks they can attack the United States and Canada with a fait accompli, a decapitation strike or even just enough to degrade our military capability, to keep us from projecting power and responding to something over there, they might want to do that in order to pen up our power projection forces that are resident in North America. That's why it's not enough to think of this air problem as a lesser included set of the big nuclear problem but as something different.
I think one of the other witnesses commented on the Operation Spiderweb phenomenon. What happens when a spiderweb or something much more robust is brought to bear on, say, bomber bases, aircraft or something like that. Since everyone else is quoting Gen. Glen D. VanHerck, I will as well. He said in the past that this comes down to what it is that an enemy might do to bring us to our knees. We don't want to be brought to our knees. We want to be able to deflect that kind of attack, so that every single day our adversaries wake up and think, “Today is not the day to attack.”
