He plays a significant role in helping more than 120,000 Iraqi Jews flee to Israel in the early 1950s. He is elected to the Knesset in 1952, serving there until 1959, and again from 1974-1992. He becomes Minister of Police and Internal Affairs, and holds several ambassadorial posts to Africa in the 1960s.
