Clinton was very invested in creating Israelis-Palestinian peace, I don’t think he would have been as passive on the Palestinian death toll as Biden was at the beginning of the conflict. Obama was willing to go up against Netanyahu when he wanted something (like the Iran Nuclear Deal), so I think it’s likely he would have also had a stronger response to the Israeli genocide, as long as it was politically expedient for him. On most issues, I think Biden has actually been better than the (admittedly very low) expectations I have for the Democratic party, but I think he’s actually worse than his party’s predecessors on Israel.
