Lehi and the Irgun were jointly responsible for the massacre in Deir Yassin . Lehi assassinated Lord Moyne , British Minister Resident in the Middle East , and made many other attacks on the British in Palestine . On 29 May 1948 , the government of Israel , having inducted its activist members into the Israel Defense Forces , formally disbanded Lehi , though some of its members carried out one more terrorist act , the assassination of Folke Bernadotte some months later , an act condemned by Bernadotte 's replacement as mediator , Ralph Bunche . After the assassination , the new Israeli government declared Lehi a terrorist organization , arresting some 200 members and convicting some of the leaders . Just before the first Israeli elections in January 1949 , a general amnesty to Lehi members was granted by the government . In 1980 , Israel instituted a military decoration , an " award for activity in the struggle for the establishment of Israel " , the Lehi ribbon . Former Lehi leader Yitzhak Shamir became Prime Minister of Israel in 1983
