>[Iron Dome] has been activated to intercept about 27 percent of the approximately 180 rockets fired between Monday night and midday Wednesday.

Measure what you manage. The system's success rate for attempted targets is a valid measure. But it is also a dangerous one on which to solely rely. A devious commander, seeking only to maximize this metric, would limit Iron Dome interceptions to only those strikes which he is supremely confident it can successfully intercept.

May I suggest a complimentary statistic of people injured, and property damaged, per missile fired from Palestinian territory regardless of whether Iron Dome engages or not. This measures, in the long run, both (a) how effective Iron Dome is when it engages and (b) how good Iron Dome is at deciding whether or not to engage. B is missing today. I think it is a crucial component to manage.
