Probably because Uncle Bibi is an unadulterated bully that has convinced itself and its billionaire American backers (who have politicians in their pockets like a hanky they blow their noses on when the fancy suits them) that no matter how egregiously it treats the Palestinians as it plows them under with its American supplied weapons and financial support, they have God on their side, so there is no amount of carnage they can cause that should be considered to be too much. They play the “holocaust card” at every turn even though the vast majority of its citizens were not alive when it happened, but they play it because they can tell themselves they are the victim, always the victim and are therefore morally critically untouchable. Uncle Bibi and his minions in America have spent decades carefully cultivating this persona of victimhood, and it has proven to be successful beyond their wildest dreams, the manipulation is complete, America is the dog being wagged by the tail. For example the propaganda elicited by Israel, the lies it tells, are universally proven to be lies and yet Uncle Bibi marches on unscathed. In the meantime the propaganda from the Palestinian side are condemned as lies by using the word of Uncle Bibi as proof they are lies, and is assumed to be lies by many Americans because it paints Uncle Bibi in a different light than those Americans want to believe (like I said, the manipulation is complete).
