Borders of Israel - Border With Lebanon

Border With Lebanon

The United Nations in June 2000 was called upon to decide the Lebanese border to determine whether Israel had fully withdrawn from Lebanon in compliance with Security Council Resolution 425. This line came to be called the Blue Line. At the same time, the United Nations did not have to consider the legality of the boundary between Lebanon and the Israeli-controlled Golan Heights, as that was not required for the purpose of Resolution 425. Accordingly, the Armistice Demarcation Line between Lebanon and the Israeli-controlled Golan Heights is expressly not to be called the Blue Line.

The Blue Line, which the UN had to determine was the line of deployment of the IDF before March 14, 1978, when Israel invaded Lebanon. In effect that line was recognised by both Lebanon and by Israel as the international border, and not just as the Armistice Demarcation Line of 1949 (what is commonly called the Green Line) following the 1948 Arab–Israeli War.
