According to a news article which you can read in full here,
A Facebook campaign which emerged earlier this month, urging frugal Israelis to emigrate has caused an unprecedented level of controversy over the role of economics in public opinion in Israel, as well as the strength – or weakness – of Zionism among younger Israelis.

However, an official tally indicates that emigration appears to be at the lowest rates in recent history, with liberal estimates stating that just 15,000-18,000 Israelis are living in Germany today.
Why would Jews ever want to live in Germany, the country that perpetrated the Holocaust, murdering 6 million Jews, who had never done them any harm?

According to Eliyus Paz, the head of the World Bnei Akiva in Germany, as quoted in the news article:
“People who are coming to Berlin are, more than they are saying, ‘Germany is cheap,’ they are saying ‘We have something against Israel,'” Paz stated, adding that they are “mocking Israel” by saying that the country responsible for the Holocaust is “better than Israel.”
“the country responsible for the Holocaust is better than Israel.” What a revolting development this is!
Regarding the Facebook page which urges Jews to live in Germany, this quote is from the article:
Much controversy has been raised over a Facebook page urging Israelis to move to Berlin, with some saying the page is “anti-Zionist.”
I can’t give you the URL of the Facebook page. You need a Facebook page of your own in order to access the pages of other people.
It is not just Berlin, but other cities in Germany, that are attracting Jews. New synagogues are being built in Germany, including the new synagogue in Munich, which is shown in my photo below.

Why does this concern me? Are the Jews now saying that the Germans, who killed 6 million Jews, are better than the Israelis? I’ve never been to Israel, unfortunately. I wanted to go there, years ago, but a Jewish person advised me that it was too dangerous for a non-Jew to go there.
