Only if you ignore that there’s also a segment of Democratic voters who would reconsider support for Biden if he took a stance that they perceived as anti-Israel. Democrats are a coalition party of compromises between factions who have to work together to find as much common ground as possible in order to have any political relevance in a first-past-the-post system. Biden has to walk whatever tightrope loses the fewest votes, and he seems to think that not doing a 180 on decades of US foreign policy is the best way to do that.
It’s like he watched Beto O’Rourke commit political suicide over guns and thought “I bet I can do that on a national scale.”
