It is on the military to avoid civilian casualties.

And what would be your solution to that? accept people to flee to Israel and put them in camps temporarily until they can go back? surely that won’t provoke negative reactions…
Letting everyone roam freely also isn’t workint since Hamas has shown that they’d take any chance they get to harm Israeli civilians so they’re for sure not taking that chance.

it’s always easy to criticize something and MUCH harder to come up with a better alternative - and I’ve yet to read someone state one other than “don’t attack Gaza” which would basically be like rolling over and letting the terrorists win which surely can’t be in people’s interest…
