Context: Discussion between Zbigniew Brzezinski (President Jimmy Carter’s National Adviser) and Menachem Begin (Israel Prime Minister) over returning Sinai back to Egypt during a walk in Camp David woods, USA: hosted by President Jimmy Carter
Begin: “I want you to understand that my right eye would fall out, my right hand would fall off before I ever sign a single scrap of paper permitting the dismantling of a single Jewish settlement [in Sinai].
Menachem Begin had previously taken a solemn oath before God and the people not to let Egypt regain the Sinai. The issue was resolved by letting the Israeli Knesset make the decision and not him.
