A tidbit connection I did recently is the Ukraine and Hassidic Judaism.
Every year in jewish new years, thousands of hassidic jews pilgrim to Ukraine, even during the war, to visit the tomb of Rabbi Nachman, the founder of Orthodox Judaism (which is btw, not older or more strict than other forms of judaism).
Its also when prostitution peaks in Ukraine. Famous for having a diverse menu of ages and such.

While I did mention before the intent of making Ukraine a new israel and the Khazarian stuff, the Hassidic angle is a curious detail. Hassidics are famous for being anti-zionists.
