Right you are. And today’s leftist leaders (both in Europe and here) have made the calculation.
Pay only lip service to the Jews. But do nothing significant to help them. Because the Muslim vote is more important than the Jewish vote.
Plus Muslims tend to get violent when challenged. So it’s better to appease them.
I seem to remember from my history books that when anti-semites are appeased, things go badly. But maybe this time it will be different (not).
