Task: Question Generation
Input (English): The status of East Jerusalem in any future peace settlement has at times been a difficult issue in negotiations between Israeli governments and representatives of the Palestinians, as Israel views it as its sovereign territory, as well as part of its capital. Most negotiations relating to the territories have been on the basis of United Nations Security Council Resolution 242, which emphasises "the inadmissibility of the acquisition of territory by war", and calls on Israel to withdraw from occupied territories in return for normalization of relations with Arab states, a principle known as "Land for peace".
Output (English): What is the principle of normalization of relations with Arab states?
