I think I'll focus not on the expose o Zionism here, but what Herzl and Arthur Ruppin actually believed.

Such as Herzl:

The anti-Zionist Jew is a kike and an arrow is aimed at his breast.

Ruppins ideology on race was exactly the same as Hitlers. Furthermore, thr Rothschilds and many Jewish banking houses refused to give Herzl any some of money. Nonetheless, Herzl asked dozens of Jewish banking houses to provide funding for their cause before anti-Semitism turned into pogroms. He claimed that if Rothschild refused he [Herzl] would have to turn to measures to cause destabilization and pogroms.

Hegalian dialectic.

Rothschild eventually funded the project when he realized its commercialization potential.
