I used to be a Trotskyist. Their (the WSWS's) explanation of the Nazi obsession with Jews goes something like this: The real hatred of the Nazis was towards the working class who had dared to make a revolution in 1918 that ended Germany’s great patriotic war. However the lowly workers themselves couldn’t possibly have done this without all those damn Marxists. There were quite a few Jews among the union leaders and in the social democracy. So it was not the Rothschild-style bourgeois Jews that bothered Hitler but the Luxemburg-style Marxist Jews. Eventually an entire ideology emerged about race and nation. Add to this, the low cultural level of lumpen, peasant, and shopkeeper elements; the panic and desperation of the petty-bourgeoisie on the verge of ruin and looking for scapegoats, and the decadence of capitalism as a whole; and you get a nasty brew.
That’s the closest thing to a decent explanation I’ve ever heard on the subject. I still don’t really get Nazism's and its obsession with the Jews. Does anyone?
