Because Bibi knew the election was upcoming and Biden was extremely weak and unpopular at home. He had zero incentive to work with the Biden administration. And if the administration completely stopped providing weapons, just call them weak, pro Hamas terrorist supporters who hate our allies. My point is had Harris won she would have been in a stronger position at home since she wasnt looking at an election and Bibis buddy Donald Trump would have finally been out of the picture (well in his 80s by the next election)
