Felix Klein, newly appointed by Mother Merkel's Government as a envoy to "handle" Germany's freshly imported Jew hate, offered his thoughts on the phenomenon (archived):

It is quite understandable that those who are scared for the safety of their children would consider leaving Germany. I hear this from my own Jewish friends. But we must do everything to avoid that.

There is no word yet on whether Klein, Merkel, or others are considering bringing back exit visa requirements as part of that everything.
