after their expulsion during the Sinai Campaign. During the Cuban Revolution, HIAS set up operations in Miami to relocate the Jews of Cuba. During the 1960s, HIAS rescued Jews from Algeria, Tunisia, and Libya and arranged with Morocco's King Hassan for the evacuation of his country's huge Jewish community to France and, eventually, Israel. Of almost one million Jewish refugees from Muslim countries, about 80,000 were resettled by HIAS. In 1965, HIAS was instrumental in the passage of an immigration law that finally replaced the National Origins Quota, eliminating decades of ethnic admission policies for the US. In 1968, HIAS came to the aid of Czechoslovakia's Jews after the suppression of the "Prague Spring", and to Poland's Jews after Communist Party factions started an internal fight using an anti-intellectual and anti-Semitic campaign, whose real goal was to weaken the pro-reform liberal party faction and attack other circles (1968 Polish political crisis). In 1975, following the fall of Saigon, HIAS was asked by the State Department to aid in resettling 3600 Vietnam refugees. It was at that time that HIAS broadened its mission, Since that time, the organization has continued to provide support for refugees of all nationalities, religions, and ethnic origins. This has been stated as: "Originally HIAS helped Jewish refugees; now HIAS is Jews helping all refugees." In 1977, HIAS helped evacuate the Jews of Ethiopia, which culminated in several airlifts to Israel. However, in 1981, the Jewish Defense League protested the "lack of action" to rescue Ethiopian Jews by taking over the main offices of HIAS in Manhattan. In close coordination with Israel, HIAS played a central role in rescuing Jews from Syria and Lebanon. In 1979, the overthrow of the Shah in Iran precipitated a slow but steady stream of Jews escaping the theocracy of that country, home to one of the world's oldest Jewish communities. In addition, to helping Iranian Jews, many Iranians for religious e.g. Baháʼí faith or political reasons were also aided by HIAS. The Soviet Jewry exodus Beginning in the mid-1960s, HIAS returned to the work initiated at its founding – assisting immigrants escaping Russia with their arrival and resettlement needs in the U.S. Close to a century later, a new Jewish exodus from the previous Russian Empire – now the USSR – started with a trickle of departures. Throughout the entire era of Soviet Jewish exodus, HIAS' operations centered around two beliefs:
