In completely unemotional terms - civilian deaths ARE collateral damage and to some extent unavoidable in urban warfare.
There is no getting around that. You can’t negiotiate with terrorists whose only goal is destruction.
Hamas and their masters are positively gleeful at the civilian carnage and the western handwringing,
it’s exactly what they want.
During WW2, we firebombed German cities, to destroy the manufacturing infrastructure / road and rail networks - the alternative was surrender and becoming occupied like mainland Europe, many thousands of German civilians were killed, as were the hundreds of thousands of European civilians killed as the Allies fought their way from Normandy to Berlin - was that murder?
No, it was the unfortunate consequence of war.
