His handlers are betting that the Jews' loyalty to the Democrat party is greater than their concern for Israel, and that's probably a good bet

Nothing has broken that loyalty yet, so I doubt that this will:

Biden to go to UN Security Council to force temporary cease-fire on Israel, halt Rafah offensive

JERUSALEM — The Biden administration is reportedly taking its goal of a temporary cease-fire in the Israel-Hamas war to the U.N. Security Council as early as Tuesday. 

The administration is said to have proposed a draft U.N. Security Council resolution which in part would call for a temporary cease-fire and call on Israel not to go into Rafah in the Gaza Strip. 

According to Reuters, the U.S. text states in part that it "determines that under current circumstances a major ground offensive into Rafah would result in further harm to civilians and their further displacement including potentially into neighboring countries."

Richard Goldberg, a former NSC official during the Trump administration, told Fox News Digital, "The United States should be vetoing pro-Hamas resolutions, not proposing them. By putting forward a resolution calling for a ceasefire and opposing Israeli military action in Rafah, the White House is effectively pushing for Hamas to survive to massacre another day. This is a complete betrayal of U.S. interests and values."

Whatever one’s opinion of the wisdom of going into Rafah, for the US to turn to the UN, an institution whose members hate America, Jews, and Israel, is a complete betrayal of our country, as well as Israel. It lends an air of legitimacy to a morally (and fiscally) bankrupt collection of crooks and petty dictators, and implies that the UN has some say in this conflict. Bah.
