Jews are not central to the Dajjal (antichrist) story. It is only mentioned that his army of followers will have tens of thousands of Jews in it coming from the east (could be China, or anywhere between china and the Levant). The foretold events point to a post-“Israel” world.

The “tree” hadith is relevant. And the trees are not magical or “homicidal”. The hadith points to the high-tech military/surveillance apparatus turning on “Israel” at some point (with a single exception). The hadith just drew the picture in a way the people of the time could comprehend.

Between the aftermath of the “State of Israel” experiment, and the supposed appearance of the antichrist, it wouldn’t be surprising if many Jews, especially religious non-Zionist ones, sought refuge and lived among Muslims again, like they always did throughout history. Given the raising extreme vitriol against all Jews, in the west and elsewhere, in part due to the actions of the world Zionist-capitalist cabal, I would say this could be more likely to happen than not. This of course assumes that things will shake out in a way where Muslims, or some of them at least, will actually rule themselves, and the colonially-manufactured client mini-states of today will also be no more.

Maybe that cabal will switch sides at some point and go to China. And that’s how they will become a part of the antichrist movement. Or maybe not. The world could change many time over between the end of “Israel” and the supposed appearance of the antichrist. We don’t know.
