Deterrence is always tactically superior to defensive counter-attack.
Successful deterrence is, but one must weight a given deterrence strategy against the ability to counter-attack. If we are talking about strategies, then as you say there is no guarantee that deterrence works. So deterrence as a strategy not guaranteed to work is not necessarily superior. Additionally as I allude to at the bottom of the quote I think it's a false dichotomy. Good deterrence sometimes leads into a good counter-attack.
One of the biggest reasons is that it is impossible to possess credible deterrence without also possessing the ability to execute a strong defensive counter-attack.
I disagree; even without taking into account bluffing, there are plenty of positional or verbal deterrence strategies that do not have anything to do, per se, with counter-attacking.
However, the ability to execute a strong defensive counter-attack can be possessed and have no detterent value whatsoever.
I agree, but it's an apples and oranges comparison, since many effective deterrence/evasion/disruption strategies have nothing to do with a gun. Additionally, you're dangerously close to implying that a gun is the only or best deterrence strategy, which I strongly disagree with.
The most effective defense is one in which there is an element of deterrence which you present publicaly, and an additional defensive counter-attack capability that you keep in reserve and secret.
I think I agree but don't necessarily see how this advocates for OC in any way whatsoever, except for the very generic "live and let live" OC advocation, of which I count myself a subscriber. It actually seems to promote CC, to me.
That being said, there is no deterrence that can be guaranteed to work 100% of the time, and there is no defensive counter-attack that can be guaranteed to work 100%.
I totally agree, which is why I prefer to derive my deterrence from dynamic strategies tailored to the situation and that lead into surprise counter-attacks, rather than a static constant-on strategy of revealing the info that I'm carrying.
