The department was headed by Yosef Karo, and Yisrael served as his assistant.

. He was introduced to Ben-Gurion and reported on the activities of his department. During that meeting, Ben-Gurion decided to rename the "Jewish Department" to the "Internal Department." Yisrael succeeded in his role and became an unofficial spokesman for the Shai. He maintained fair relations with members of other underground movements, who were under his department's surveillance. At the Shai headquarters, Yisrael earned the nickname "Isser the Small," both due to his short stature and to distinguish him from "Isser the Great," Isser Be'eri (Birenzweig), who joined the Shai headquarters in 1947 and was tall in stature. Be'eri later became the head of Israeli Military Intelligence, but was dismissed following the Ali Qassem Abed al-Qader affair. In 1947, Yisrael was appointed the commander of the Tel Aviv District of the Shai, responsible for gathering intelligence from Arab

to assess Jordan's intentions and whether they planned to go to war. The agent reported that the Jordanians intended to join the war, and Yisrael hurried to inform Ben-Gurion.

). The service under Yisrael's leadership had to be built from scratch, determining its principles, organizational structure, and methods of operation. One of the basic principles he established was that the employees of the organization had to be full-fledged government employees, with appropriate ranking, salary, and social benefits, without the special privileges and perks typically associated with secret service personnel in undemocratic countries. Another principle set by Yisrael was that employees had to maintain a high moral standard, with no criminal background and no adventurist tendencies. This principle, he claimed, was not adopted by military intelligence at that time, leading to scandals such as the Avri Elad and Mordechai Kedar cases. Yisrael also decided to break down the political and party-based barriers that existed before the establishment of the state. He employed, without distinction, former members of the Haganah, Palmach, Irgun, and Lehi in the Shin Bet and later in the

. From his appointment until his resignation on 25 March 1963, Harel also held responsibility for the Shin Bet, where the head of the Shin Bet was subordinate to his directives. This dual role earned Harel the title "Mossad Chief" or "The Head of Israeli Security Services." To emphasize this hierarchy, the Mossad was officially referred to as the "Central Institute for Intelligence and Security" (later renamed the "Mossad for Intelligence and Special Tasks"). After Harel's resignation in 1963, the dual role was abolished and has never been reinstated. Isser Harel was the only individual in the history of the State of Israel to hold a position that consolidated both internal and external intelligence responsibilities, giving him unprecedented power. Harel participated in leadership meetings of the ruling

party, where he would also report on the activities of opposition parties. For eleven years, Harel served as the head of Israeli intelligence services, during which time the organizational structures and operational methods of the security services were formed and refined. These years also saw significant intelligence and security achievements. In 1953, the Shin Bet successfully exposed the right-wing extremist underground, leading to the prosecution of its members. However, some critics claimed that Harel exhibited authoritarian behavior and tended to bypass legal boundaries when necessary, as seen in the case of Operation Bren, where the body of an Israeli officer suspected of selling military secrets to Egypt was secretly disposed of following his accidental death during his arrest.

This surveillance continued under the Shin Bet. In this context, Harel authorized an operation that later became a source of significant controversy: the surveillance and wiretapping of

Shortly afterward, Sneh and his followers broke away from Mapam to form the "Left Faction," advocating a more openly pro-Soviet policy, and eventually left the party altogether. Although the wiretap operation created a political firestorm, the intelligence gained from it was significant. Harel was also instrumental in the arrest of Aharon Cohen, one of the leaders of Mapam and a prominent figure in the

party. In response, Harel authorized the funding of a competing weekly magazine, "Rimon", which was designed to attract readers away from "HaOlam HaZeh" by offering a similar, sensational style of journalism. The effort was a failure—Rimon failed to gain significant readership and quickly folded. This attempt to subvert a legitimate media outlet using state funds was widely criticized and is considered a low point in Harel's career.


Resignation and the German Scientists Affair

Harel's long and distinguished career came to an end in 1963, in the wake of the German scientists in Egypt affair. This incident involved a group of German scientists who were assisting the Egyptian government in developing advanced rocket technology, which posed a significant threat to Israel. Harel viewed the presence of these scientists as a grave danger and launched a covert campaign to intimidate and disrupt their work. Mossad agents in Europe attempted to discourage the scientists through a variety of means, including sending threatening letters and engaging in sabotage. However, after two Mossad operatives were caught in

ordered the Mossad to halt its operations. Harel, convinced that the scientists represented an existential threat to Israel, strongly disagreed with Ben-Gurion's decision. He believed that Ben-Gurion underestimated the danger and felt that the Prime Minister's focus on maintaining positive relations with

was misguided. Despite Harel's protests, Ben-Gurion stood firm. Faced with this disagreement, Harel resigned from his post as head of the Mossad and Shin Bet in March 1963. His resignation marked the end of an era in Israeli intelligence, as Harel had been the central figure in shaping the country's security services since their inception. Harel's departure from the intelligence community left a lasting legacy, but also set the stage for years of tension between him and his successors, particularly Meir Amit, who replaced him as head of the Mossad.


Major achievements

Harel's tenure was marked by major intelligence successes. One of the most notable was the acquisition of the

Public service

After his resignation, Harel maintained a low profile for several years, focusing on writing about his experiences in the intelligence community. However, in 1965, amid the political turmoil surrounding the split within the ruling

. Harel accepted the position, but his role was largely symbolic, and he resigned in June 1966 after concluding that he lacked meaningful authority in the government. Harel continued to be involved in public life through his writing and his outspoken views on national security matters. His books, such as ''The House on Garibaldi Street'' and ''The Great Deception'', offered insights into the world of Israeli intelligence and earned him recognition as a leading authority on security issues.


Political career

In 1969, Harel entered politics, joining the National List, a party founded by Ben-Gurion after his split from the Labor Alignment. Harel was elected to the
Knesset The Knesset ( , ) is the Unicameralism, unicameral legislature of Israel. The Knesset passes all laws, elects the President of Israel, president and Prime Minister of Israel, prime minister, approves the Cabinet of Israel, cabinet, and supe ...

Later life and death

In his later years, Harel became a prolific author, writing extensively about his experiences in intelligence and security. His books, including ''The House on Garibaldi Street'' and ''Security and Democracy'', became key texts for understanding Israel's intelligence operations during its formative years. Harel's views on security, especially his staunch opposition to any form of accommodation with enemies of the state, influenced Israeli policy for years after his retirement. Isser Harel passed away on February 18, 2003, at the age of 91. He is remembered as one of Israel's founding fathers of intelligence, whose leadership and vision helped to secure the state during its most vulnerable early years.

Isser Harel remains one of the most influential figures in the history of Israeli intelligence. His pioneering work in establishing and leading the
