The jews and the Left are not monolithic.

Team A(sshole) are the true Communist believers. Activists, organizers, journalists, the people who believe they've already won and are eager to get on with the killing.
Team B(anker) are the corporate types that fund and control the Left.

The Palestinian genocide has uncovered a major divide within the Left. Team A is using their standard playbook, sit-ins, protests, the occasional riot, and endless reporting about sad Victims of Oppression. But this time, the Oppressor is oganized jewry, in the form of Israel. All of Team B is Zionist, including the few non-jews, and cannot tolerate any challenge to Israel's moral legitimacy.

Team B has realized that without working class White men to do their killing, they are on a direct ride to genocide. So they are working to re-elect Trump, as much as they hate him, and lighten up the anti-White rhetoric just enough to re-staff the military,until they can kick off the wider WWIII in style and kill all the Whites.
