Under authoritative international rules, Israel’s mid-March targeting of senior Hamas commander Marwan Issa was law-enforcing. Among other egregious crimes, Issa was a key planner of the October 7 rampage against Israeli civilians. Maj. Gen. Tamir Hayman, former chief of Israeli military intelligence, accurately described this Palestinian terrorist leader as Hamas’s “strategic mind.” To fully understand this law-based action, geopolitical context is necessary. In essence, the world legal structure compels a vigilante system of justice. It is against the background of continuing global anarchy that terror-beleaguered states must identify and operationally shape their counter-terrorism options.
