First, I'm well aware of IDF operating procedures. I have never approved of its bombing high rise buildings. That's neither here nor there.
My opinions come from a lifetime of reading history and accounts of soldiers. I don't know if it's in this story, but I have pointed out that there is some military value in bombarding Gaza. The question is how much value and at what long-term cost? I go into that here: https://medium.com/@maxrottersman/dispassionate-take-on-israels-gaza-tactics-504c5b4cb2c4
