Isreal can’t just rely on Iron Dome. Interdicting the supply line is a good strategy. So is killing the people who shoot the rockets, as well as killing anyone who might do so.
“Except, here’s a true story: Back in mid-June, during the great Paris weapons show, the Rafael pavilion was absolutely the busiest around, and everybody wanted to look at the new, exciting, Iron Dome system, the greatest achievement in rocket defense ever. But by the end of the show, Rafael hadn’t made a single sale. The Arrow sold well, other systems did great – Iron Dome wasn’t moving. So they contacted their big clients, the serious ones, and asked what gives. And those clients told them no one except Israel has any use for these things. Because in any normal, sane country, if some hooligans were to start targeting civilians with rockets – the army would go and kill them.”
Everyone oohed and ahhed, but nobody wanted it. Granted Israel is between a rock and a hard place. If they send the Army in, obama would cut them off so fast their heads would spin.
