answer:I am not sure how the Jews wound up in Europe, I think probably we travelled to where the work was or where we were not being killed or enslaved, but that is a guess, my history knowledge isn’t great. As far as Jews moving back to Israel; Jews were buying up property and returning to “Israel” before WWII. I believe many returned to the land of Israel in the late 1800’s and early 1900’s, Many considered themselves Zionists. I don’t find your question antisemitic or offensive by the way.
