The United Nations Security Council votes 11-1 to allow the Palestine Liberation Organization to participate in a Security Council debate (without voting rights).

The Palestine Liberation Organization (PLO; Arabic: , Munaamat at-Tarr al-Filasniyyah) is a Palestinian nationalist political and militant organization founded in 1964 with the initial purpose of establishing Arab unity and statehood over the territory of former Mandatory Palestine, in opposition to the State of Israel. In 1993, alongside the Oslo I Accord, the PLO's aspiration for Arab statehood was revised to be specifically for the Palestinian territories under an Israeli occupation since the 1967 ArabIsraeli War. It is headquartered in the city of Al-Bireh in the West Bank, and is recognized as the sole legitimate representative of the Palestinian people by over 100 countries that it has diplomatic relations with. As the official recognized government of the de jure State of Palestine, it has enjoyed observer status at the United Nations (UN) since 1974. Due to its militant activities, including acts of violence primarily aimed at Israeli civilians, the PLO was designated as a terrorist organization by the United States in 1987, although a later presidential waiver has permitted American contact with the organization since 1988. In 1993, the PLO recognized Israel's right to exist in peace, accepted Resolution 242 of the United Nations Security Council, and rejected "violence and terrorism". In response, Israel officially recognized the PLO as a legitimate authority representing the Palestinian people. However, despite its participation in the Oslo Accords, the PLO continued to employ tactics of violence in the following years, particularly during the Second Intifada of 20002005. On 29 October 2018, the Palestinian Central Council suspended the Palestinian recognition of Israel, and subsequently halted all forms of security and economic cooperation with it.

The United Nations Security Council (UNSC) is one of the six principal organs of the United Nations (UN) and is charged with ensuring international peace and security, recommending the admission of new UN members to the General Assembly, and approving any changes to the UN Charter. Its powers include establishing peacekeeping operations, enacting international sanctions, and authorizing military action. The UNSC is the only UN body with the authority to issue binding resolutions on member states.

Like the UN as a whole, the Security Council was created after World War II to address the failings of the League of Nations in maintaining world peace. It held its first session on 17 January 1946 but was largely paralyzed in the following decades by the Cold War between the United States and the Soviet Union (and their allies). Nevertheless, it authorized military interventions in the Korean War and the Congo Crisis and peacekeeping missions in Cyprus, West New Guinea, and the Sinai Peninsula. With the collapse of the Soviet Union, UN peacekeeping efforts increased dramatically in scale, with the Security Council authorizing major military and peacekeeping missions in Kuwait, Namibia, Cambodia, Bosnia and Herzegovina, Rwanda, Somalia, Sudan, and the Democratic Republic of the Congo.

The Security Council consists of fifteen members, of which five are permanent: China, France, Russia, the United Kingdom, and the United States. These were the great powers that were the victors of World War II (or their successor states). Permanent members can veto (block) any substantive resolution, including those on the admission of new member states to the United Nations or nominees for the office of Secretary-General, but there is no veto right in emergency special sessions of the General Assembly. The other ten members are elected on a regional basis for a term of two years. The body's presidency rotates monthly among its members.

Resolutions of the Security Council are typically enforced by UN peacekeepers, which consist of military forces voluntarily provided by member states and funded independently of the main UN budget. As of March 2019, there had been thirteen peacekeeping missions with over 81,000 personnel from 121 countries, with a total budget of nearly $6.7 billion.
