In March 1949, when Iraqi forces withdrew from Palestine and ceded their positions to the smaller Jordanian delegation, three Israeli brigades depoerated themselves in advantageous positions in Operation Shin-Tav-Shin and Operation Uvda. The operations enabled Israel to renegotiate the ceasefire line in the southern Negev (which allows access to the Red Sea) and the Wadi Ara area in a secret agreement reached on 23 March 1949 and incorporated into the general ceasefire agreement. The green line was then redesigned in blue ink on the south map to give the impression that a move of the green line had been made.  The events that led to a change in the Green Line were an exchange of fertile land in the Bethlehem region under Israeli control and the village of Wadi Fukin, which was handed over to Jordanian control. On 15 July, when the Israeli army expelled the population of Wadi Fukin after the transfer of the village to Israeli-occupied territory under the ceasefire agreement between Israel and the Jordanian kingdom, the Joint Ceasefire Commission decided on 31 August, by a majority, that Israel had violated the ceasefire agreement by de-dering villagers on the demarcation line. , and decided that the villagers could go home. However, on 6 September, when the villagers returned to Wadi Fukin under the authority of UN observers, they found most of their homes destroyed and were again forced by the Israeli army to return to Jordanian-controlled territory.  In the Knesset, the then Minister of Foreign Affairs and future Prime Minister, Mosche Sharett, called the ceasefire lines “temporary borders” and the former international borders on which the ceasefire lines, with the exception of Jordan, were based, “natural borders”.  Israel did not claim territories beyond these territories and suggested them: On March 16, 1954, the Israelis of the settlement of Un Gev began plowing 130 dunes near the settlement and belonged to the Arab population of the demilitarized Nuqeib. , in violation of the oral agreement reached in Samara in 1950, under which both parties should retain the country in question until the problem is resolved.
The ceasefire agreements were clear (on Arab pressure) that they did not create lasting borders. The Israeli-Egyptian agreement states that “the ceasefire border must not be regarded as a political or territorial border and is demarcated, without prejudice to the rights, claims and positions of one of the parties to the ceasefire, with regard to the final resolution of the Palestinian question.”  The 1949 ceasefire agreements are a series of ceasefire agreements, signed in 1949 between Israel and neighbouring Egypt, Lebanon, Jordan and Syria to officially end official hostilities in the 1948 Arab-Israeli war and establish ceasefire lines between Israeli and Jordanian-Iraqi forces, also known as the Green Line.
