Israel starts to use DroneSwarms. See the comment on that page.
Except worse because in 50 years time society will have been transformed by the proliferation of drone technology. Either, in the attempt to keep the population under control, Israel will have been led to impose an Orwellian solution of positioning robot observers in every Palestinian home and flying them along behind every Palestinian youth. Or the Palestinian terrorist will have replaced rockets with autonomous drones able to range independently for weeks within Israeli territory before suddenly popping up and killing people. Most likely we'll see an arms race between both tendencies, and a tragic continuation of the waste of lives, wealth and happiness of both peoples.
