This paper analyzes the assassination of Lord Moyne, the British Resident Minister of the Middle East, in 1944 by the extremist Jewish group Lehi and the effect the incident has carried throughout the last sixty eight years in both Britain and Israel. The weight of the memory of the assassination as well as how terrorism is defined becomes poignant with the 1975 peace agreement between Egypt and Israel following the Yom Kippur War. With an eye to how Israel has continued to make the assassination part of its national identity and Britain’s reaction in 2012 with the death of Yitzhak Shamir. Through the lens of this assassination the use of memory and the definition of terrorism have continued to be reinterpreted by both the governments of Britain and Israel.
