They should understand the necessity of a reaction if so. 64 seems to struggle with this.
Like I have suggested, if Hamas gave one ounce of care for their civilians, maybe they shouldn’t have launched this pogrom, nor embedded themselves in civilians, nor roadblocked those fleeing. Israel are not setting out to deliberately kill civilians, as the order to evacuate demonstrated, so I cannot see it as ‘genocide’ any more than the bombing of Germany was during WWII. It’s not ideal, but how does Israel free hostages and protect itself from Hamas, who have signalled its desire to destroy Israel, without the risk of civilian casualties? My point was less about the difficulty of removing Hamas, more about the difficulty of an idealistic solution.
