This opening chapter examines whether international law is relevant to the Arab-Israel conflict. The conclusion reached is that although the dispute is political ideological and territorial; nevertheless, international law has played an important role, and will continue to do so. All parties desire that their positions be seen to be legally legitimate, such legitimacy is a political asset as regards both the other party and vis-à-vis third parties. The international language of international relations is, largely, the language of international law; this is particularly true as regards the United Nations and international organisations. Israel and the Palestinians are engaged in an intensive campaign to persuade world public opinion of the legitimacy of their respective cases. Legal precedents, although not binding, play a highly useful role in assisting the parties to reach agreement. The same is true for dispute settlement mechanisms of international law. Finally, the object of negotiations is to reach agreement. The principle that international agreements are binding is a principle of international law and lawyers, based on international law, will examine their validity and context.
