It makes perfect sense. The original Pilgrim Puritan Founders of the USA were cosplaying as Jews from the Old Testament; to the point where they condemned the Catholics for having things like religious icons. And if you look at things today, the biggest backers of Israel among the Goyim are Evangelical white Christians; the spiritual descendants of said Pilgrims. And every "America First" candidate practically runs on a pro-Israel ticket. Granted, the Dems do too, but the Right beats them on the Zionist card. Kamala isn't as far into Zionism as Trump is.
So it makes perfect sense that they're pro-Jews; the Puritans back in England, when they ruled it under Oliver Cromwell, welcomed the Jews back after centuries of exile that started with Richard the Lionheart. And now the modern American Right-wingers who saw the Puritans as the good guys gave the Israelis a blank check.
You cannot separate the American Right from Zionism. The European Right might hate Jews, but the normie American Right will always see the Jews as allies. Especially since they see the Jews as an inspiration for their own religion. They are more than happy to stomp all over the Gospel of Jesus Christ, which called for making disciples out of all nations to be united in one body in Christ. But they will never turn their backs on Israel and the Jews.
Trump tried to make Canada the 51st state, which is hilarious; the real 51st state is, and will always be, the Nation of Israel.
