Had Iran sought to catch Israel by surprise, it could have unleashed the ballistic missiles that were deployed in the final phase of the attack, whose flight time is 10-12 minutes, without any warning. Moreover, the overwhelming majority of these missiles were aimed at Israeli military bases — that is, Iran refrained from targeting civilian population centers. Only one person was seriously wounded as a result of the attack: a 7-year-old girl from an unrecognized Bedouin village, who was injured by a fragment of a missile that was intercepted by the Iron Dome (unrecognized villages, home to over 100,000 Arab Bedouin citizens in the Negev/Naqab desert, are not provided with shelters, leaving them completely exposed to rockets and falling shrapnel). Immediately afterward, Iran announced that as far as it was concerned, the issue was settled, unless Israel insisted on retaliating further.
