There is a super interesting and complicated discussion to have about the pragmatics and morality of concerted military action versus stochastic civil violence. Unfortunately, thread conditions on HN aren't conducive to it; the discussion will instantly devolve (via people joining in) to valence arguments about the cause of this or that campaign of violence. I genuinely think you'd need a moderation regime designed from the ground up to support a productive conversation about this topic, which, for good reasons, HN doesn't provide.
