The United Nations has set up surveillance and communication services to monitor established ceasefire lines. In addition, discussions on the implementation of the ceasefire led to the signing of the separate 1950 tripartite declaration between the United States, Britain and France. They pledged to take measures inside and outside the United Nations to prevent border crossings or ceasefire lines. He also presented their commitment to peace and stability in the region, their refusal to use or threaten violence, and reaffirmed his opposition to the development of an arms race. These lines continued until the six-day war of 1967. The Palestinians did not participate in the drawing of the Green Line and rejected UNSC 242 and stated that they were not asking for an independent Palestinian state and that they were calling it refugees. Since 1976, most PLO members have accepted the line before June 1967 as the basis for the creation of a Palestinian state.  The majority of Israeli public opinion opposes the return to the borders before 1967. A 2011 study showed that 77% of Israelis oppose, for security reasons, a return to lineages before 1967, even if it would lead to peace between Israel and neighbouring Arab states.  On April 22, 1953, at sunset, fire broke out in Jerusalem along the demarcation line for about 4 kilometres. It took two hours for the ceasefire agreed by UN observers to enter into force. The next day, shots were fired early in the morning and afternoon. Twenty Jordanian victims, 10 dead and 10 wounded.
Six Israelis were wounded. The Jerusalem incident has been investigated by United Nations observers. After reviewing the evidence gathered, General Riley stated in a report to the Security Council on the violation of the ceasefire [S/3607] that it seemed impossible to determine who fired the first shot.  GaA Israel-Lebanon was signed on 23 March 1949 by Lieutenant-Colonel Mordekhai Makleff for Israel and Lieutenant-Colonel Tawfiq Salim for Lebanon in Raes Naqura. The Israeli troops, who had withdrawn from parts of southern Lebanon they occupied in the summer of 1948, agreed to set the limits of the marking of the armistice along the former international borders, thus introducing greater stability in Israeli-Lebanese relations for more than twenty years. After the “Black September” of 1970, the Palestine Liberation Organization (PLO) and the various Palestinian guerrilla groups moved the site of their operations from Jordan to the refugee camps in Lebanon, making the Israel-Lebanon border a recurring battleground. Israel attacked southern Lebanon in March 1978 and again in June 1982 and occupied it briefly. After the 1982 invasion, Israel failed to push Lebanon to reach a peace agreement and the border region remained aggravated instability for nearly two decades; The presence of a UNITED Nations special force (UNIFIL) has made little difference.
