'During World War II, Lehi initially sought alliance with Fascist Italy and Nazi Germany, offering to fight alongside them against the British. On the belief that Nazi Germany was a lesser enemy of the Jews than Britain, Lehi twice attempted to form an alliance with the Nazis. During World War II it initially supported fascism, declaring that it would establish a Jewish state based upon "nationalist and totalitarian principles". After Stern's death in 1942, the new leadership of Lehi began to move it towards support of Joseph Stalin's Soviet Union.In 1944 Lehi officially declared its support for National Bolshevism. It said that its National Bolshevism involved an amalgamation of left-wing and right-wing political elements, however this change was unpopular and Lehi began to lose support as a result.
Lehi assassinated Lord Moyne, British Minister Resident in the Middle East, and made many other attacks on the British in Palestine. It was described as a terrorist organization by the British authorities. Lehi assassinated United Nations mediator Folke Bernadotte and was banned by the Israeli government. The United Nations Security Council called the assassins "a criminal group of terrorists," and Lehi was similarly condemned by Bernadotte's replacement as mediator, Ralph Bunche. Lehi and Irgun were jointly responsible for the massacre in Deir Yassin.
Former Lehi leader Yitzhak Shamir became Prime Minister of Israel in 1983.'
