The difference being the IDF has consistently gone to pretty significant lengths to warn civilians and give them time to evacuate.

True, but then to bombard from the air destroying whole buildings and killing many civilians to get to a few combatants under the building is not an ethical or moral move either. You don't get a get out of jail free card for notifying up front, you have to follow through.

Telling someone to evacuate is not enough, you have to verify they have evacuated. If they have not, you should be instead sending in ground troops, and yes with a larger cost in lives and political turmoil, but that is the ethical way.

Non-combatants are not supposed to be involved in combat.

Bullshit. There's evidence of some warnings but with literally thousands of air strikes a week there literally isn't the resources to warn everyone like they did during the "cease fire". And you don't get 10,000 civilians dead in a month by warning them.

Hamas supporters hate this one trick!
