Abstract This empirical paper studies rocket attacks and defenses in Israel during operations Protective Edge, Pillar of Defense, and Cast Lead, plus the Second Lebanon War. It analyzes publicly available counts of rockets, fatalities, casualties, and property damage. The estimates suggest that interceptor deployment and civil defense improvements both reduced Israel’s losses slightly during Pillar of Defense and substantially during Protective Edge. They also imply that interceptor performance during Pillar of Defense may have been overstated. Ground offensives were the most expensive way to prevent rocket casualties. Interceptors were at least as cost- effective as military offensives, and improved over time. Without its countermeasures, Israel’s rocket casualties could have been over fifty times higher during Protective Edge. These results imply that Israel’s rocket concerns were more justified than critics admit, but its military operations were less worthwhile than intended.
