Levanon continued his work from Israel by joining Nativ's Tel Aviv headquarters. He set up a unit called Bar, composed of Israeli diplomats in the delegations to the U.S., UK, and France. Bar was tasked specifically with encouraging the immigration of Soviet Jews to Israel and even received funding from the CIA to aid its cause. After Joseph Stalin's death in 1953, the apparent desire of the Soviet government to improve its image in the West allowed Bar and Nativ to more aggressively press the cause of Soviet Jews.
