Israel has one of the most sophisticated military-industrial complexes in the world, with vast expertise in electronics and remote sensing specifically. If they wanted to build a precision-guided kinetic weapon for targeted assassinations of Hamas fighters in dense urban areas, they could have done it without a second thought. Instead they spend their efforts on building an oppressive surveillance apparatus and robotic machine guns to better punish rock-throwing teenagers, and lob bombs into population centers to deal with Hamas in the area.

re: the tunnels… these things tend to happen when you herd millions of people into a walled ghetto, cut off access to resources, and leave it to be run by what is effectively an overgrown prison gang. The fact that Hamas is willing to use civilians – nearly half of them children – as human shields does not excuse the use of indiscriminate force in calling that bluff. Again and again and again, Israel has made it abundantly clear that there is no war crime it will not excuse in the course of these retributive strikes, because the lives of Palestinians are worth less than nothing to Israeli leadership.
