The most recent cycle of anti-Jewish violence and unrest in Europe will likely pass.
I like to think that Europeans in particular have learned from the Holocaust and certainly the majority oppose such actions.
Israel is of course always there as a last option for safety to any Jew under the law of return.
I think that Europe is phasing out the Jews. The assimilation rate is very high - 80% in France. I hope you're right about the recent spate of violence.
I've been receiving mail from the Holocaust Museum, World Jewish Congress, Simon Wiesenthal Center etc.. They seem to be very concerned about all of this. They claim it's getting worse.
Based on what I saw in Israel my last several trips, I think Israel would need drastic changes to become a place of refuge for Europeans and Americans.
I experienced a lot of antisemitism growing up on LI, NY. I always failed to understand why my father didn't go to the ADL.
