The bully accused American Jews of "disloyalty" — disloyalty to what, one wonders — for being loyal Americans and voting for the Democrats who (more or less) support their views of what is good for the US, instead of supporting his right-wing extremist flunky, Netanyahu.

I think his aim is to build up the irrational anti-semitism which is one of the bases of his support, and an illogical reason is as effective as a logical one.
