I think in general the west has gotten way to used to the US Military's precision and restraint, and so the West has forgotten that civilians die in war, often in higher numbers than the soldiers. Starvation, disease, and collateral damage are all a thing, as well as deaths from infrastructure destruction.
That's why we talk about war being waged as "a country" not just it's military (except the US, but don't get me started on that). The country as a whole will often pay the price for that war.
Germany found out (twice), Japan found out, most of SE Asia found out, more recently Ukraine and Syria have found out.
Palestine is about to find out. You don't get to just divorce the "civilian" population from the actions of the government and large militant factions. There are consequences. That goes both ways. Israel has failed to either defeat or find peace with it's neighbors, and the consequence of that is currently being felt by Israeli citizens.
