That's all cool. But it's just standard deflection from the tens of thousands of deaths that the Biden administration directly enabled. And Arabs living in Israel doesn't magically make all the very public statements that Israel made (like that they wanted to level the city to the ground, and displace its population once and for all), repeatedly and throughout the entire Gaza operation just go away.
Israel didn't make those statements. Specific members of radical parties did. Imagine judging a country by their worst people. I bet your country would fare quite badly.
He didn't even go as far as condemn the radical parties that you mentioned. Absolutely no red line, or anything. Just complete carte blanche. Again, even Bush or Reagan didn't let Israel do whatever they want with no political repercussions. Israel knew back then that some lines couldn't be crossed without losing American support. With Biden, they did whatever they wanted, said whatever they wanted and took advantage of that.
