As I said, potential for screwup is high. But the leader does not has to be Netanyahu.

There’s multiple levels so the answer is “sort of.” Very generally, the Minister of Defense (or equivalent) has a national defense council that will have heads of armed forces and maybe a few senior civilian members. The council creates the overall battle plan with specific generals or admirals creating plans for specific battles or campaigns that conform to the overarching goals set by the defense council. The Prime Minister has a cabinet. The cabinet will receive info from the defense council. Intelligence agencies and departments involved with any economic warfare. The PM and cabinet can give direction to individual councils and departments to coordinate the overarching strategy of the entire country. The defense council will then adjust plans based on Cabinet’s directives. The PM is probably given detailed briefings of battlefield progress and aims for the military for the short-, medium-, and long-term for the conflict and can veto specific plans. But the PM won’t help to plan attacks or modify those plans usually. That’s the purview of generals and admirals.
