It does not have to be that way. Look at what's going on in the Donbass. It is war, it is happening in a densely populated area. Both sides make heavy of the artillery.

But the death count is like x100 times less.

Because they're not willingly trying to kill as many civilians.

(I agree with the rest of your points though)
