That requires amazing precision and dedication, bombs are designed for mass killing. Yet even the inflated numbers show less than 1 casualty per bombing. Those numbers don't separate the number of actual combatants that were killed (as opposed to civilians).
I'm not for bombing in general, I think it's a terrible weapon. But the ground invasion will probably kill a lot more civilians as it's harder to fight in narrow streets. Stray bullets and shelling kill a lot of innocent bystanders.
Overall, Israel doesn't have a choice here. The Hamas is still holding civilian hostages. It is still firing missiles on civilian Israeli cities. It is the reason this is happening.
I'm sorry for the Palestinian people but they will probably be better off without the Hamas.
