One of the major issues regarding Sicut Judaeis Non to my mind is that it proved ineffective in curbing Jewish influence/power over time.
Yockey wrote that any time you have an alien group living within the realm of another group, the alien group, by it's very presence, harms/disturbs the indigenous group. If he is correct, than I don't see how the Jews would be able to continue living in Western Christian countries without fully converting and denouncing Judaism, without distorting the culture and life-ways of said Western Christian countries.
I think there is added difficulty in the fact that the modern West is a-religious. This poses serious problem regarding the possibility of assimilating the Jews. Whereas in the past at least one could attempt to assimilate the Jews into the Western culture by a total conversion to Christianity, this is no longer an option, given that the governments of the West are now secular, and, as pointed out by Jones, a secular Jew is still a Jew, as secularism does not negate the anti-Logos nature of the Jews.
I saw some very inconvenient poll a while back that showed Jews in the united States view White Protestants the most unfavourably out of any other demographic group. The Jews are not just "waging a war against the Catholic Church". I would have more sympathy for the Catholic Church in this war but they cowtow to Jewish historical mythology and world-hegemony generally (apart from certain traditionalist factions). I'd be very interested in reading what Jones has to say about the current state of the Roman Church.
Protestant Evangelical, Charismatic, or Pentecostal denominations aren't much better. They view Jerusalem as the linchpin of the Apocalypse and hold the belief that a nation that turns its back on Israel turns it back on God. They are seriously pro-Israel and Zionist. That's why the GOP panders to them with all that pro-Israel jazz.
It's more than just mere Zionism. Certain American Protestant denominations are to the point of literal jew worship.
I can confirm that the Catholic school I attended went to great lengths to insure we viewed the Jews sympathetically. I suppose they were concerned that we would draw the conclusion that since the Jews killed our savior, and continue to deny him, that they were to be looked down upon.
They never went so far as some of the evangelicals I know that have basically accepted dual covenant theology, but at times there seemed to be almost an unstated view that this was the case, although there were a few teachers/priests there that no doubt believed that if one was not under the Church of Rome they weren't getting into paradise.
That being said, I am amazed when I recall just how much time was spent insuring that we were all dissuaded of any possible anti-semitism. I remember learning about the Jews choosing Barabbas over Christ, and being urged repeatedly that this was the fault of the Romans not the Jews. Granted, no one at that time in that school probably gave much thought to any of that, it was all just school work and such for us.
My Catholic Grandmother vehemently disagrees with my Evangelical Aunt about the relationship between the state of Israel and Christians.
