That’s a reasonable response, except that I wasn’t complaining about your use of the word guarantee but that just because two things may both be “no guarantees” of anything doesn’t mean they have the same efficacy. Chemotherapy is no guarantee you’ll survive cancer. Neither is thinking happy thoughts. This doesn’t mean that both have the same efficacy, and it doesn’t mean that treating them as equivalent non-guarantees of survivorship is immune from objection.
How much transparency is required in a war context? If the US targeted civilian military scientists (let alone specific military figures) during a war, would the Rule of Law require they be first added to a non-secret kill list on the basis of non-secret evidence, as the result of some sort of judicial process (which would presumably be stronger than a kangaroo court)?
