Yachin In 1961, with the coronation of Hassan II, the government relaxed the laws on emigration to Israel and even facilitated it. Operation Yachin was a clandestine agreement with Israeli authorities and the American Hebrew Immigrant Aid Society that entailed a payment to Morocco for each Jew that left the country for Israel. Over the next three years, more than 80,000 Moroccan Jews emigrated to Israel. By 1967, only 60,000 Jews remained in Morocco. The Six-Day War in 1967 led to increased Arab-Jewish tensions worldwide including in Morocco. By 1971, its Jewish population was down to 35,000; however, most of this new wave of emigration went to Europe and North America rather than Israel. France for a time was a destination particularly for Moroccan Jews with European educations, who had economic opportunities there; one study of Moroccan Jewish brothers, one of whom settled in France and the other in Israel, showed that 28 percent of the brothers who settled in France became managers, businessmen or professionals (compared to 13 percent of their Israeli brothers) and only 4 percent unskilled workers (compared to over a third of their Israeli brothers). Moroccan Jews in Israel, far more numerous, enjoyed less upward mobility: 51 percent were blue-collar in 1961 and 54 percent as late as 1981. 21st century Despite their current small numbers, Jews continue to play a notable role in Morocco. The King retains a Jewish senior adviser, André Azoulay. They are well represented in business and even a small number in politics and culture. Jewish schools and synagogues receive government subsidies. Several Jewish museums throughout the country cater to the growing interest in preserving Moroccan Jewish heritage and history. However, Jews were targeted in the Casablanca bombings of May 2003. King Hassan II's pleas to former Moroccan Jews to return have largely been ignored. In 2004 Marrakech had an aging population of about 260 Jews, most over the age of 60, while Casablanca had between 3,000 and 4,000 Jews. A 2014 figure says there are about 2,500 Jews still living in Morocco. As of 2018 the total of Jews in Morocco is 2,200. In 2019, the State of Israel was home to 472,800 Jews of Moroccan descent, around 5% of the nation's total population. In 2013, it was revealed that there is a rapidly growing trend of Moroccan-Jewish families sending their sons to study at the Jerusalem College of Technology in
