The sick thing is, it's the more intelligent racists (like David Duke) who blame everything on the Jews.
Because if you actually stop and think about it for a moment, in the West, at least, blacks, hispanics, Arabs, etc., don't have the financial or political power to actually make white people's lives bad. But there is a ready-made other that can be made to appear so: the Jews.
The even sicker thing is that a lot of these same racists and anti-Semites (like Steve King) will hide their grotesque anti-Semitism behind their support for Israel, which is actually because of an even deeper anti-Semitic position, that of Christian eschatology, in which, according to the Book of Revelation, Israel must exist for the apocalypse to come about (though to do that they'd also need to destroy the Al-Aqsa Mosque to rebuild the Temple, but that's fine in their books because they hate Muslims, too), and then, during the apocalypse, Jesus will return and force every Jew either to convert to Christianity or be killed.
Combine that with Jews who think that every Jew needs to move to Israel in order for the Messiah to return, and damn anyone else who was already living there, and Muslims who consider it all theirs (it once having been Muslim land, just like much of, say, Spain), and you have a recipe for unending conflict and human suffering.
