Who Is The Antisemite Again Christian's?

 I have long wondered why Americans are so keen to help Israel, especially in this time when they are committing genocide against the Palestinians, and i got an answer in one of my comments years ago that it was because America is very religious and because the Christian vote is a very large one, the politicians back Israel to keep them on side which all makes sense, abhorrent and misguided when you see what the Israeli's are doing, but from an American political stance, i can see that.
Now I am religiously very ignorant and reject any notion that any God of any flavour exists but the Christian and Jewish love-in is a peculiar one so when i was introduced to a Rabbi, i took the chance to ask him why and the reason was quite eye-opening.
Zionism, is a political and religious ideology that espouses a Jewish state in Palestine with as much land, as many Jews, and as few Palestinian Arabs as possible in accordance with Biblical prophecies mentioned in the Old Testament.
The belief is that once the re-establishment of Jewish sovereignty in the region is complete, this will herald the Second Coming of Jesus Christ and he will return to Earth after his ascension to Heaven 2,000 years ago and judge the living and the dead, something which 58% of American Evangelical Christians believe will happen hence the support for Israel as they see not an abhorrent mass killing of people and ethnic cleansing of a region but as them preparing the way for Jesus to come back again.
Now if you suspend belief and believe in a Christian God (or any God come to that) then i can see how that makes sense and why religious Christians support them but there is a kicker at the end for Jews which the Rabbi tried to sweep over, and that is that Judaism would cease to exist afterward.
The final part after Jesus does he's thing is that all Jews, as per the same Biblical prophecy, would then have to reject Judaism and adopt Christianity as the one true faith which to my mind means that the Christians are backing Israel only because it will usher in the end of the Jews.
That is worth tucking away for the next time some loopy religious types harasses me for Antisemitism because i don't want to see innocent Palestinians killed, because where as i just want to see an end to the death and destruction on all sides, you are backing Israel because you want Jews eradicated for good so who is the Antisemitic one out of us?
