Further to my interview below with Mark Steyn, and his observations about France-do read this article from the Washington Post about the exodus of the Jews from France.
Jennifer Sebag's grandparents left North Africa to escape Islamic antisemitism, and settled in France.
Now, she must leave France with her young family for Israel because of Islamic antisemitism.
Note the story of the Jews, and their host countries-it's not "if" but "when" to leave.
That's the entire "why" of Israel.
