Anti-Semitic talk and thought have been the most medieval tools for controlling, deflecting, and moving mobs and, at times, producing a little extra money for the feudal nobility by way of plunder accompanied by theft and murder.
I have on deck a similar excerpt from Michael Kellogg’s book, _The Russian Roots of Nazism: White Émigrés and the Making of National Socialism, 1917–1945_ (Cambridge: Cambridge University Press, 2005; online 2009). but I think what you may read by Walter Laqueur will give you something to think about.
The Soviet Union picked up a share of the pieces — relationships — after the Nazi defeat in WWII, and it exploited anti-Semitic sentiment to build a base for itself.
The medieval history of religion gets a little complicated. Ruling Christians in Hungary in the 12th Century formed laws to discriminate against Jews and Jewish potential and accomplishment, and then upon activation applied the same laws to Muslims.
I’ve taken the stance with anti-Semitism x feudalism and tribalism that associated conflict and cruelty are really about replacing the medieval mode and worldview with what has become politically and spiritually modern — democratically checked and distributed political power; multicultural inclusion; a great measure of compassion and secular humanism in the functional aspects of law, and where beneath such law, all are treated as equal.
The thought may at first seem spotty as President Putin handily sustains possibly the most pro-Semitic Russia in Russian history, but as one visits Moscow’s relationships with Assand and Khamenei, Hezbollah and Hamas (and PFLP) plus autocrats like Erdogan and Orban (add in Le Pen but perhaps not the now well-briefed Trump), Moscow’s medieval facets would seem unmistakable. Add to that the cruelties so well demonstrated in Syria and the cloaked “hybrid warfare” in Ukraine that would seem to amount to not much more than recognizable old infiltration accompanied by massive disinformation (for the misguiding of the masses, and much more of Russians — the 93 percent of Russians who may read and speak only in Russian — than of anyone else) and the onset of conventional war.
The inspiration for the post came by way of a Muslim convert to Christianity who had expressed enthusiasm for modern Israel, calling it a “Hebrew state” and an inspiration for the world.
Not shortly after publishing this piece, I found a well-known figure boasting of a recently attended Christian, Jewish, and Muslim colloquy and querying the presence of a “clash of civilizations”. My response:
There is a “clash of civilizations” — but it’s not the one we have been led to believe exists, i.e., some thing between the Muslim and Christian worlds. That “clash” doesn’t exist in any meaningful reality: what does exist is the struggle of the modern world to displace several worlds — Christian, Jewish, and Muslim — remaining mired in medieval outlooks, politics, and practices.
