Having read the articl ( I know, against FR rules) the Rabbi didn’t appear to say that there was no future for Jews in Europe. Now I would agree with those sentiments if he expressed them, but did he actually say that?
"There are 25,000 Jews in Brussels, 18,000 in Antwerp and the rest live in smaller places. There has been aliya to Israel as well as emigration to Canada and the US. People understand there is no future for Jews in Europe," he said.
