We have traced a genealogy of exterminationist Jew hatred from National Socialism to Islamic Jihadism. The branches of the tree, the web of interrelations, are intricate and complex, yet the influences and the parallels are clear. Abdul Al'a Maududi, Hasan al-Banna, and Michel Aflaq were admirers and students of Adolf Hitler, Alfred Rosenberg, and Johannes von Leers. Haj Amin al-Husseini was connected, both ideologically and politically, to al-Banna and the Brotherhood, as well as to Adolf Hitler, Adolf Eichmann, and Heinrich Himmler; among his most notorious protégées was Yasser Arafat. Al-Husseini also had ties to Iraqi Baathist Kairallah Tulfah, the guardian and mentor of Saddam Hussein. The Brotherhood branched out to establish itself in the Sudan, first under Hasan al-Turabi and then under Omar al-Bashir.
