Disagree on this one, Dr. Jones.
Mamdani is a standard liberal Zionist: claim to recognize the humanity of Palestinians (not a big accomplishment), two state delusion, and reducing the issue to secular humanism. His policies aren't much different than the official US position against settlements. He vocally micromanages Palestinians by condescendingly opposing the right to armed resistance, which is the position of all Soros funded Liberal Zionist ("pro Palestine solidarity") groups, as if he should have any position on armed resistance as the Mayor of New York (he should just shut up and focus on New Yorkers). Soros funded Mamdani.
Mamdani's politics are shaped by the radical liberal Trotskyites of the DSA, and they're basically Liberal Zionists underneath all their clamor for Palestine.
Massie has a more firm position than Mamdani in some ways, even though Massie is not officially anti Zionist. Mamdani will also support cultural Zionism such as LGBT, etc
