Zionism, Crypto-Judaism, and the Biblical Hoax
The Devil's Trick: Unmasking the God of Israel
The Holy Hook
Yahweh’s Trojan Horse into the Gentile City
How Yahweh Conquered Rome
Christianity and the Big Lie
Israel as One Man: A Theory of Jewish Power
The Arabian Cradle of Zion
Moses, Muhammad, and Wahhabo-Zionism
