Omar Amin (born Johann Jakob von Leers; 25 January 1902 – 5 March 1965) was an Alter Kämpfer and an honorary Sturmbannführer[1] in the Waffen-SS in Nazi Germany, where he was also a professor known for his anti-Jewish polemics.

[6] He was a district speaker and leader of the National Socialist Students' League,[4] and in 1933 signed the Gelöbnis treuester Gefolgschaft, the "vow of most faithful allegiance" to Adolf Hitler.

[6] Jeffrey Herf reports that in December 1942 Leers published an article in Die Judenfrage, a journal which belonged to the anti-Semitic intellectual world, entitled "Judaism and Islam as Opposites".

The following passage is part of the original text: In 1945, Leers fled from Germany to Italy, where he lived for five years, then in 1950 migrated to Argentina, where he continued his propaganda activities.

[6] In Buenos Aires, Leers became editor of Der Weg and praised the American neo-fascist Francis Parker Yockey and his book Imperium for its understanding of Russia, which was heavily influenced by Oswald Spengler's concept of "pseudomorphosis".

One of those whom Engdahl assisted was Johann von Leers, who "arrived in Malmö in 1947, and ... got to Buenos Aires, where he edited a paper that became a communications channel between Nazis in Europe and those who ended up in Latin America".

There, he converted to Islam and changed his name to Omar Amin, as a gesture to his benefactor, and became the political adviser to the Information Department under Muhammad Naguib and Gamal Abdel Nasser,[4] as well as being friendly with al-Husseini.
