Such a thing shows that Israel has little positive to offer Israelis, many of whom want to go the the Diaspora. So, they just play the "fear" card instead of a positive campaign as to why Israelis should stay in Israel. Its laughable. Sorry to say it, but Ahad ha-Am was wrong - much of the Jewish creativity today comes from Jews in the US and not from Israel.
