Maybe he can offer this after Hamas' defeat:
- Support changes in Israel government to have a hard look at the Haredi group of Jewish people and illegal settlements within West Bank. I got this idea from conversing with a Israeli and he pointed to Haredis.
- Peacekeeping forces within West Bank and Gaza to prevent further wars and illegal settlements.
- Bolsters belief of cohesion with each other.
I do think Biden is in the correct not to trust the civilian death tolls given fog of war, and the issue with Hamas as a group. That being said, he shouldn't support the current government of Israel either.
Also, if you're downvoting, you need to understand that yes, I understand that there are problems within Israel, but there is no reason to support Hamas either. If you understand that, then where's the issue here?
