As I mentioned, the best chance for the US to influence Israel is for it to not take an adversarial role. It's like negotiating with a hostage taker. (I hate oversimplified analogies in foreign policy, but this one works really well). A hostage negotiator tries to sympathize with the hostage taker because it's the best way to get the hostages out safely. America has tried to thread the needle between putting pressure on Israel and remaining supportive. It hasn't had much success, but it's the best course open to us.

I am not of the opinion that moral considerations don't belong in foreign policy, but moral judgements like assigning "blame" can be antithetical to achieving moral ends. The second you label a foreign government as "genocidal" you lose all ability to influence them with anything but military force.

I actually agree with you that America gets a lot of the blame for what is happening but, most of the fault comes from things before October 7. I also fault Biden for a lot of that, and I think he has been far too over the top in supporting Israel publicly. What I think they are getting bad press for is the broad strategy of trying to restrain Israel while maintaining the relationship.
