Yitzhak Rabin operations during Israel's War of Independence. He joined the newly formed Israel Defense Forces in late 1948 and continued to rise as a promising officer. He helped shape the training doctrine of the IDF in the early 1950s, and led the IDF's Operations Directorate from 1959 to 1963. He was appointed Chief of the General Staff in 1964 and oversaw Israel's victory in the 1967 Six-Day War. Rabin served as Israel's ambassador to the United States from 1968 to 1973, during a period of deepening U.S.–Israel ties. He was appointed Prime Minister of Israel in 1974, after the resignation of
Yitzhak Rabin at Kfar Giladi. He trained his men in modern tactics and how to conduct lightning attacks. After the end of the war the relationship between the Palmach and the British authorities became strained, especially with respect to the treatment of Jewish immigration. In October 1945 Rabin was in charge of planning and later executing an operation for the release of interned immigrants from the Atlit detainee camp for Jewish illegal immigrants. In the Black Shabbat, a massive British operation against the leaders of the Jewish Establishment in the British Mandate of Palestine, Rabin was arrested and detained for five months.
