The argument is that the IDF is targeting enemy combatants, and not deliberately targeting civilians (unlike, e.g. Hamas). The existence of non-combatant casualties alone does not imply terrorism.
The whole thing of Hamas is embedding itself and its infrastructure in the civilian areas. If civilians are requested to evacuate, informed about the fact their houses are used by Hamas and the rocket launchers, rocket factories, tunnels and electric infrastructure to support all of that is going to be targeted, then perhaps it is not exactly fair to use words “bombing civilians” as a matter or fact?
not deliberately targeting civilians (unlike, e.g. Hamas)
This is not as simple as it looks. Hamas does indeed target civilians, but what really put the wind up Israel on October 7 was that they successfully overran 2 military bases and mounted a serious attack on a third, although that was repelled. Per Israeli media, the government there had significant prior warning (months or maybe as much as a year) but dismissed the intelligence in the belief that Hamas lacked the military capability and was just LARPing.
