If ‘no bomb/missile ever is a war crime’, then .. there is no such thing as “terrorism”, either. (Although the argument could be made that there is no such thing as ‘terrorism’ at all, and that indeed, the word terrorism is merely a propaganda crutch used to justify atrocities against so-called ‘lesser cultures’ deemed inferior by the same institutions which used to use the ‘n-word’ to justify their atrocities in decades past, too, before that became difficult to do ..)
You can indeed commit war crimes with sticks too, though, incidentally.
“The IDF attacks civilians. It uses perfidy to indiscriminately attack the civilian population of its enemies. It, too, ignores the laws of war.”
There is no way to continue justifying acts of terror being committed by your in-group, without also become equivalent to the terrorist of your out-group.
