As far as i can tell, Biden is historically pro isreal. Openly refers to himself as a zionist. His religion demands that isreal gains power in order to attempt to make the bible only embarrassingly incorrect. His parents instilled in him that due to WWII the Jews are justified in taking the land and this includes their current encroachment. He has been the main and highest paid donar recipient of pro isreal groups for his 5 decades in politics . Changing course now would force a critical evaluation of his 5 decades of blindly giving unwavering support to Israel and recognition that Palestinians are people. Also the US has made enemies of everyone in the region, and Israel gives us a “foot hold” there.

All this makes the finding of a genocide a mere consideration for his polling numbers.
