There are deeper root causes for the political class' dedication to Israel to the point of genocide. While I suppose capitalist class dictatorship could be euphemistically referred to as money, the political class true believers in the project like Genocide Joe and by extension his lockstep veep, see a strategic value in Israel's constant violence as a European settler colony. Biden even had a famous quote about the need for an Israel, it is about American domination of the entire region to control the petrodollar and disrupt a locus of national independence.

These are cynical people, not simply sellouts. They think genocide is worth it. They also want your vote so they do some kabuki, present the half-assed aesthetic that they care about "ceasefire" while maintaining intense material support for the genocide. They are banking on their electorate being accepting of genocide.
