Haaretz, Why the Mossad must remain an intelligence service for all Jews. Quote: "Two units were designated as the successors to the Mossad Le'Aliyah Bet, which was disbanded in 1952. The more secret of the two was the Mossad's Bitzur unit, tasked with overseeing the immigration of Jews from countries where their lives were in danger as well as protecting Jewish communities in the Diaspora. The other, Nativ, encouraged immigration from the Soviet Union and Eastern Europe, and after the fall of the Iron Curtain was charged with issuing immigration visas, establishing cultural centers and keeping track of any manifestations of anti-Semitism"
