Because they are still mad Khazaria is gone. It's why they they are gleefully killing Christians in Ukraine and Russia right now. Khazaria was the one place they took over to the point where judaism became the state religion. They consider it theirs and will never give it up as the Northern Empire in Greater Israel. I have seen lots of jews leaving Israel recently on social media. I imagine this is where most are going. They already go there for pilgrimages often.
